Fix Nforce related lockups

Rebster · Posted: Tue Mar 23, 2004 1:38 am Post subject: Fix Nforce related lockups

Anyone new to Gentoo and has an Nforce(2) based mainboard should get the patchset found here:

https://forums.gentoo.org/viewtopic.php?t=146381&highlight=

Build your kernel:

1. Without apic support
Causes some nasty lockups on my system.If you can get it to work
on yours then the more power to you.

2. With alsa and your sound card driver in the kernel and not as a
module if using onboard sound.
Will cause rmmod to segfault during shutdown and you'll then
have to do a hard reboot.

3. Without Preemptible Kernel
Same results as 1.

After buiilding my new kernel (2.6.4) I was able to emerge OpenOffice on tty1 while logged in as a different user running the following (all at the same time) on tty2:

X with Icewm
Rox pinboard
the Gimp
Mozilla (surfing the net)
Emelfm2
gedit

All with no slowdowns and no skipping of any kind.OO took 4 1/2 hours to build and I was using my pc 90% time.

Everything listed above can be found in the Gentoo forum.I'd like to thank everyone who helped me and especially Steel300 for the patch and a stable kernel.
If anyone has anything to add that might be helpful then please do.

well... I have an nforce2 card and I'm using 2.6.5_rc1-love2 WITH apic, alsa modules and preemptive kernel enabled... and my system hasn't had a lockup in months...

This is a most delicate matter.. I've been using mm-sources for a while but decided that an update to 2.6.5-gentoo wouldn't be that bad. However, the computer began hard-locking with no possible way to "soft-reboot" so I had to reset it. This was happening most frequent when I listened to music through xmms. I'm running it with noapic nolapic and acpi=off now and it's been stable till now :-)

I've read about some incompatibility (?) between apic and nforce2-based boards (I've got an Abit NF7-S 2.0) which would cause it to hard-lock. Most likely what I suffer from...

Turning off APIC on my nForce2 mobo solved many problems for me. It's due to shared IRQ's - which APIC has stuff to do with.

nForce2 is groovy, well, it works.

Try using 2.6.5-love4, it really spanks the fart out of my apic problems

For those wanting to try the nforce 2 with apic and are still having issue with love 5 these to forum post with the associated patches worked for me. I could actually burn a cd with apic on, it was a surefire way to cause a crash before.
