IOKitwaitquiet() timed out waiting to write kernel symbols

Well, i'm using a MSI S260 laptop !
I don't know if the mothercard used nForce, i suppose !

It's only IDE so i can't disabled it ...

I will post here the technical characteristics this evening at home. I'm at work now.

I will try with an usb mouse too ...

I too suffer from this problem but only if I have the onboard IDE controller enabled within the bios. If I switch it off my machine boots very quickly without that error. I think its an nforceATA problem on some machines that use a mixture of SATA and IDE controllers. Is your machine using an nForce motherboard?

Yes, I have had the same problem for a long time.

Strangely enough, if I don´t have any USB-things connected to my machine it takes about 5 minutes to boot, but if I have my usb-mouse & keyboard, or usb-wifi, or something like that connected(this trick doesn´t work with all USB-things, just some of them), then it takes 1 minute and 10 seconds. :-S
But I still get that iokit timed out problem.

I´m using a Acer Aspire 5104wlmi hackbook... I don´t really have any bios-settings except for a choice of a startup-disk...
It has a ATI Radeon Xpress 1100 chipset, S-ATA disk... and I am currently using an AppleATIATA kext which I found in one of the threads here on infinitemac...

well.well... i have the same problem like your.i use a nForce chipset like MCP65.
and i use an usb keyboard and usb mouse. disable ATA use SATA.it still boot with IoKitwaitquiet error.after loginwindow seesion started.the screen was black but has singe.about 5min the screen back and show the desktop . i still don't know why for a long time …

Does this help any?

Nforce4 Get rid of waitquiet timeout →

Do you have any PS2 mouse or keyboard?

If not, try renaming this file:

/System/Library/Extensions/ApplePS2Controller.kext

to

ApplePS2Controller.kext.bak

- or simply delete it.

then delete

/System/Library/Extensions.mkext

- and reboot.

good luck!
