Description of problem: Fast user switching (back from second account to first) results in a crash of X back to command line of a rapidly repeating nouveau error message which cannot be interrrupted. Use of power switch required to shut down machine.
Version-Release number of selected component (if applicable):
How reproducible: From the testday liveCD, Create second account, fast switch to second account, then switch back to first account.
Steps to Reproduce:
Additional info: This immediately runs the CPU to max and all fans in the laptop go to full speed. Honestly I was more interested in getting the system shut down before something overheated than getting a quote of the error message.
Computer is an HP Pavillion laptop model: dv9904 with nvidia 7159 vid chips.
Attempting to suspend also produces the above results.
the repeating message is as follows:
nouveau 000:00:12.0: PFIFO-INTR 04000/0000-Ch 0
I have a suspicion I know what's causing this bug, as a test/workaround could you try the nouveau.vram_pushbuf=1 boot option?
I'd be happy to, if you'll give me very specific instructions on how to do so.
The last two attempts resulted in, "Unknown boot option ignoring."
That message is fine, the kernel itself doesn't know about the option but nouveau will listen to it!
Ok. It failed immediately upon trying to switch users this time. Same message, same actions needed to shut it down.
EDIT: Actually suspended, but repeated error coming back up.
Can you update to kernel 2.6.31-23.fc12 and retry please, this should be fixed.
