For a few months now, I've been seeing occasional kernel panics that
would happen every few weeks. I'm not exactly sure when they started,
but I definitely see them in 2.6.29 and 2.6.30, and never saw them in
2.6.25 and earlier. They happen with 32 bit and 64 bit kernels.
Today I managed to capture an oops with netconsole; it's attached. This
seems to point towards the sky2 driver.
Some hardware information:

Both of these share their IRQ with other devices:

azx_interrupt, which occurs in the call trace, belongs to HDA Intel.
Not sure if that's a clue.
Please let me know if you need additional information.

No idea. So far I've avoided 2.6.31. I'd have to run the kernel for a
few weeks and even if there were no crashes it wouldn't really prove
that the problem is fixed.

Since you are using tained(nvidia) driver, I really hate to go do indepth
fixing it. And like Mike said 2.6.26 is over a year old by now.
