Exclamation Soft and hard lockups with 1.0-8762

Greetings,

After upgrading to 1.0-8762, I'm afraid I've lost my stability almost completely.

The symptoms: occasional corruption of graphics memory resulting in bizarre font rendering, etc.

Occasional soft-lockups, successfully mitigated by Linux.

Far-too-frequent hard-locks, nothing reported on the serial console

I'm appending a soft lockup backtrace to the nvidia bug report.

I have a few questions:
0) Does this problem also reproduce with 2.6.17.8 ?
1) Which driver version were you using previously?
2) Why are you using the noapic and acpi=ht kernel parameters? Does the instability persist if you do not boot with those parameters?
3) Have you verified that you're using the latest BIOS for your motherboard?

Thanks,
Lonni

Awesome! Right as I was about to post my response, it crashed again :P

0. I'll try to personally verify this soon. I know the symptom happens with older kernels (not sure of 2.6.17.8 specifically) because I have a friend running a dual-core Opteron that has experienced the same instability problems with 1.0-8762. He does not use release candidate kernels.

1. 1.0-8178.

2. Can't boot without noapic and can't boot with normal ACPI. The board is an ASUS P5GDC-V Deluxe.

3. No, but I'm pretty sure it is.

My friend hasn't reported his identical problem (well, same symptoms anyway) yet because this forum won't take a free e-mail address. When I speak to him again, I'll fetch a copy of his bug report and post on his behalf.
