Kernel panic downloading BIG torrent file

Yes i have 4GB ram and what drivers where i should get them ?

Update.

Here is picture of kernel panic, but i am not sure if they are allways the same. "BSD process name corresponding to current thread: kernel_task" was utorrent one time i remember.

ip ix.lt/desc/34416829/

If i understand well u only download at 500 KB/s ? I am downloading at 3 MB/s + and no problems after fixing that problem with heavy disk usage.

Please list your system specifications (edit your post)!

Do you have a system with 4 GB RAM or more? Maybe you need one of the 64bit-adapted chipset drivers, mainly for nForce, VIA and so.

We corrected the issue Naquaada talks about above while in the IRC channel but I figured we would add it here too. In your case you have an nForce 570 chipset which is the same as mine. I was able to use Slashacks 64bit modified kexts to prevent freezing.

1. Remove /System/Library/Extensions/AppleNForceATA.kext if it exists
2. Copy AppleNForceATA.kext to /System/Library/Extensions
3. Entered your admin password when prompted
4. In Terminal write:

sudo chown -R root:wheel /System/Library/Extensions/AppleNForceATA.kext
sudo rm -R /System/Library/Extensions.kextcache
sudo rm -R /System/Library/Extensions.mkext

5. Restart using the boot flags:

-v -f -F

Sometimes Extensions.kextcache is not there. This isn't an issue. What we are trying to do is make 100% for sure that the cache is recreated with the new kexts. So basically we are deleting the cache and then booting with -f to force OSX to pull from the Extensions Folder

If your still having problems you can repair disk permissions in Disk Utility or by using Terminal with the following:

sudo diskutil repairPermissions /

This method can be used to install any kext you want. When installing homebrew kexts repairPermissions will make no difference as OSX wouldn't know the proper permissions to assign.

@nuttzy

I always use these commands for adding new kexts:

sudo -s
(enter your password, it's not shown)

chmod -R 755 /System/Library/Extensions && chown -R root:wheel /System/Library/Extensions

diskutil repairpermissions /

after this reboot with -f -v to recreate Extensions.mkext. Extensions.kextcache was only existing in Tiger. But please add your system specs in the signature.

@lanceomni:

Interesting that you rember things I said in IRC. I didn't Say, what is nForceLAN.kext? I'm using skge.kext on my board, but it also has a nForce LAN port. What is the difference between forcedeth or forcedeth-v ?

> naquaada - Yeah I worded that wrong. I was referring to your post about 4GB of memory and that nuttzy and I discussed it over on #infinitemac.

I thought your board, the one in your signature, had the same lan version as mine. I tried forcedeth but it didn't work out for me. Dies pointed me to nForceLan and it worked like a charm. Ive been curious as to the difference between forcedeth & forcedeth-v I remember seeing something that said forcedeth-v was the preffered version but im not sure. I might pull my nForceLan.kext and try the others just to see if they work.

Thanks for the info about Extensions.kextcache I was wondering why I have not seen that file in a while.

So all kexts need to be 755?

forcedeth.kext crashed sometimes when transferring large files over network. forcedeth-v didn't have this problem, but it's not as good as skge.kext. I'll test nForceLAN sometimes.

These kexts freeze when your system spikes during downloads (speed is too high) so I use little snitch and my router to put a cap on an instantaneous download speed (anything under 500 KB/sec I can live with). I have yet to try the skge.kext you mentioned. How is this better? right now I'm using the nForceEthernetDriver.kext (probably a variation of one of the above mentioned kexts too). Because of the editing of plist files, we are Forcing the ethernet to work with it so naturally we will get some backlash if not regulated (hence my cap). are any of the other files specifically for certain boards and not to be messed with on others?

also, just thought I'd throw my hat in on permissions

sudo -s
cd /System/Library/
chmod -R 755 Extensions/ && chown -R 0:0 Extensions/ && touch Extensions/
diskutil repairPermissions /

I've found that the touch actually makes the system think they are native extensions instead or recognizing some as non-Apple and therefore will repair all of them. Oh well, 21 more characters in the same line won't kill me if this is overdoing it. :

@n0fav0ur

forcedeth.kext is for the normal nForce LAN port (Marvell 88E8001 chipset) of my board, skge.kext is for the second LAN port which has a Marvell 88E1115 chipset.

@nuttzy

3MB/s? wow! I got about 800-900 KB/s maximum.

Kilobits per second (kbps) 8000
Kilobytes per second (kBps) 1000
Megabits per second (Mbps) 8
Megabytes per second (MB/s) 1

I am running cable which they advertise at 6 Mbps (6 Megabits per second). I am on a relatively quiet node and so I have been getting 15 - 17 Mbps down and 3 Mbps up. For example right now I am getting 15256kbps down.
15256 kbps = 15.256 Mbps = 1.907 MB/s

This being the case Naquaada would be connected at around 7 Mbps but Nuttzy you would be connected at 24 Mbps. If that is the case you must be on Fiber or something fast. What kinda of internet access is available in Europe/Lithuania?

Though correct me if I am wrong... I am wrong occationally

@nuttzyIf i understand well u only download at 500 KB/s ? I am downloading at 3 MB/s + and no problems after fixing that problem with heavy disk usage.

haha... is this what you thought I meant?

I have the capability to download via my LAN at 15Mbpsc but I limit my LAN communication...

my uncapped 802.11G gives me

I stated above that I limit my LAN connection to avoid the spikes that cause my system to KP... haven't had a KP due to my LAN since then.

I'll edit later to show you an un-capped vs capped connection...
