Osx boots on my computer in 1min and 30secs because of "IOKitWaitQuiet() timed out waiting to write kernel symbols" :( I havent found a fix for it yet either..

We could start a wiki page for this, but we'll need some more people for this, who volunteers?

My boot times are terrible probably close to 3 minutes or so mainly because of the IOKit delay as well.

I agree. The size of the Extensions folder seems way bigger than it needs to be. Don't know much about what devices need what but I'd like to help in anyway possible.

this the single annoyance i have would be nice to see footage of these quick boots. I have probably 1 of the quicker systems in this group but the boot time is bad *8O(

I agree with Lawless... YouTube your boot up times if able. It may be that boards that don't need the NForce kernel extension boot that fast, but I'm very doubtful. :-/


EDIT: As far as the wiki page goes, I'm doing research on the kernel extensions but so far it is a slow process. I've been utilizing the AppleDev website to learn more. I think the page should be accessible via this forum... maybe via an editable thread where users can write in their comments but the first main post will just be edited to make everything a little cleaner. I don't think any ONE peson should take credit for this kind of thread as then it would be a community effort.

follow-on ideas?

If you consider 20-30s fast, I'll youtube it..

I've just timed mine with a stopwatch :-B

From the time the darwin boot prompt reaches zero, it takes 26secs to reach my desktop. I don't receive any iokitwait messages whatsoever.

@Voyn1x - see, now that I believe :-d. You've got a Gygabyte board and I've seen those work that fast with my own eyes. Congrats on a great system.

Its the other boot times that hover around 15 seconds. Or those with an NForce chipset that use the kernel extension. Sometimes it just doesn't seem real enough.

Which kernel extension would that be?

NForceATA sometimes placed within IOATAFamily

I have an nForce chipset and boot at 20-30s, let me know if you want a video of that.. I'd like to see WinLinMac01's monster boot :)

ok... so what I REALLY meant was... for me with a M2N61 board and the MCP61 northbridge... it takes forever for the IOKit to work its magic.

BTW... I would love to see your boot-ups. Not because I don't believe the majority, but because then maybe I'll be able to convince my wife to let me buy a newer board ;)! :cool:

Well I finally managed to get my boot down from 2-3 minutes to 42 seconds! It was all to do with the IOKitWaitQuiet() timed out waiting to write kernel symbols error. After a little research into the error I went into my BIOS and turned off the PCI to IDE BusMaster and the On-chip IDE controller allowing only the SATA controller to remain in play. On rebooting I was astounded to see how fast my machine booted to the desktop. The only downside to this method is that I've now lost the ability to use my IDE DVD writer and SATA DVD writers don't seem to work well with the current nforceata driver.

45 seconds with prelinked kernel. Pentium M 1.73 Ghz, 5400 rpm SATA drive (no ahci) and 1.5GB RAM. That's not bad - it's faster than linux on this same machine which takes at least 75 sec or more from bootloader to hdd idle.

how do we record our boot ups?

not with the computer you are doing it with if that is what you are asking. use a digital camera and try to upload it to youtube or another video sharing site.

if your boot time is under 20 seconds, I would love to see it. please put a sound bit in the background so we can all hear that you haven't sped things up.

This isn't to prove to me you have a fast boot anymore... rather, to show off your system.

have fun with it. Cheers.

Video of verbose boot (26-27s), usually a bit faster but never under 20s like others here.. And don't pay attention to the song in the background, just to prove that I didn't use any magic ;)

@ PingunZ - Video doesn't want to load for me. The picture freezes at the boot prompt while the music continues on. Is this happening for anyone else?

P.S. nice music ;) (I know you said to ignore... but I couldn't help it... Rock out! ambient techno style!)

EDIT: oops... didn't have flip4mac installed on my macbook.... hmmm. still doesn't work..

Try "save link as" and watch it on VLC / quicktime, if it still doesn't work I'll upload a new video, sorry for the inconvenience :)

mmm. yeah, I'm jealous. I've got to talk my wife into letting me buy another monitor and a new board...

Sweet dual-monitor setup... and the boot-up time is faster than my macbook!

35 seconds with from pressing the power button to full boot. I have firewire enabled, so if I kill that I can probably go even faster. This is a laptop with 1.5 GHz Intel Core 2 Duo, 2 GB ram, and SATA disk.

When booting off my external harddrive it takes me 5 minutes...

1 min

Leopard 10.5.5
ASUS M2N
AMD Athlon 64 3800+

It boots faster then my intel laptop (Asus U3S) as well, while the laptop should boot faster..
Let me know if you need more info

about 26-30 seconds from bootloader, A8N-E, Athlon X2 3800+@ 2.5 Ghz.

aobut 1,5 minute, sometimes less. can`t use sleep so i have to boot it every time :(

It's always better to boot than to resume from sleep

Sleep is working well for me with the new XNU kernel, using S3 hibernate too! :cool:

I've a few small issues i need to iron out with usb drives, but otherwise it seems to be fine

Mine takes about a minute. Used to be about 15-20 seconds but after I installed my graphics card it seems to go to a blank screen for 45 seconds and then pops up with the desktop. Not going to argue with it and I'll leave it alone as long as the computer works.

just a quick note i have drastically reduced my boot time and got rid of the iokitwait it may be a while as i have me messing with installs for days but i will be writing some usefull info on all this. Its about 30secs now i think

I changed my mobo(Gigabyte GA-MA770-DS3) mainly because of problems with the USBs. That problem stayed, and also my boot time was the same. However, I did a new test install on another volume with the same distro from Lawless, and this new install boots in about 20 seconds!!! Waiting to see what the solution from Lawless is, cause I don't want to do new primary installation.

My boot time varies drastically. Sometimes, it only about 15 seconds, and things start right on up. Other times it stops at InterfaceNamer: timed out waiting for IOKIT to quiesce and it takes around 5 minutes. I'm running Leo4All v2 updated to 10.5.5

what I found, is that using the AppleATIATA instead of AppleVIAATA did not actually solve the problem with the iokitwait. But deleting the AppleonboardPCATA.kext did! So even my primary install now boots in about 15-20 seconds. So if you have the iokitwait and have the AppleonboardPCATA.kext, delete it and use AppleATIATA. Now everything is perfect(SATA in AHCI). PATA drives also recognized and mounted.

Cheers.

not quite on topic but i posted this over at insanely in response to a question.

somethings i know that will effect the installation of this release and others. Alot of it comes down to your hardware. Slave and master drive configs can make a huge difference. If it wont boot (install or os) with dvd as slave then try master. Bios settings have a dramatic effect on everything. The best process if you have problems is disable everything you can in the bios eg firewire on board sound etc. Then just do an install with your chipset kext. Then once you have a booting system start to add all other kexts. I am shortly going to write a bit of a guide about everything i have found about problems with bios etc. 1 thing i have found is that depending on what your bios settings are will cause the create account loop. This goes for the majority of distros not just mine.

im booting up my acer aspire one a150x with 10.5.4 in about 25secs,
a little bit slow but i can life with it :)

My Acer Aspire 5104Wlmi, boots up in 1 minute and 10 seconds.
It has an AMD Turion 64 X2 TL-56 processor, and is running iAtkos v4a updated to 10.5.5 by using Zephyroths AMD Software Update.

I have tried removing a lot of kexts(including all the ATA kexts, firewire & sata kexts), and just use the AppleATIATA kext found earlier in this thread, but still don´t see no real difference in boot-time.
I always get the "IOKitWaitQuiet() timed out waiting to write kernel symbols error", no matter what...
I have almost no BIOS options om my machine.

I'd figure this is my firs time posting =o
Thank you so much for posting this! I went from 1 minute 18 seconds (from pressing enter on darwin to when i see the dock and everything loaded) to a dramatic 33 seconds! lol and I want more!! just kiddin. and thanks for telling which one to get rid of Seawane :)

Before I head off I would love to say thank you ZEPH...this magnificant project came together safely. and im up to date as much as I can see around these forums.

Best Regards

My GA-MA78GM-S2H with LawlessPPC 10.5.4 boots about under 20 seconds (14 to be more precise - stopped that with my watch).

Maybe it's the fast CL4 memory or else, I dunno. I also erased the Extensions.mkext (the first thing I always do with a new Rig) and cleaned the final setup thoroughly with Onyx. Before I did that boot time for the OS was about 2 minutes.

Of course, boot time is from where the OS begins to load - with turning the machine on with a cold start it's total time is roughly 40 seconds (darn ACPI load time). ;)

I was wondering if there was a tip to shorten the blue screen? Cause that takes up most of the time needed to start

like 20 seconds total, takes alot longer now due to the kexts for my graphics card:-/

20 seconds here, but since i've tried the bootcamp possibility, leopard loads ntfs drivers at startup, in fact the time increased by 8 seconds :'( :)

5 minute bootup wait - time out waiting for iokit to quiesce
 

HI

I have ideneb 10.5.4 on my compaq nx5000 notebook. Bootup was taking 5 mins - hanging on:
time out waiting for iokit to quiesce

I removed iopccardfamily.kext (pcmcia driver I believe). Now my bootup is under 1 min

Complete boot-up with using 32-Bit Kernel & Extensions takes 32 seconds here - waking up from deep sleep just about 8 - so I am used to hibernate instead of shutdown. :D

45 seconds fully operational

Bare Install:
1 Minute 11.81 Seconds
24.59 Seconds Using modified IOATAFamily

After Applications:
31.45 Seconds Using modified IOATAFamily

I would swear that my boot time in 10.5 was 10-15 seconds. It was really unbelievably fast. now my boot time for 10.6 is about 25 seconds

I don't use voodoohda.kext, which usually takes most of my boot time

hey lanceomni, how do you modify IOATAFamily?
