kernel log
Kernel logs report "Watchdog detected hard LOCKUP on cpu 1". It has occurred
once per day for the last three days. Each time, it happens seemingly randomly
- monitor is turned off, I'm connected remotely via SSH but system is idle.
This is on ArchLinux with xf86-video-nouveau 1.0.7. The machine is ~2.5 years
old and has been very solid until now. My video card is: 01:00.0 VGA compatible
controller: NVIDIA Corporation GT216 [GeForce GT 220] (rev a2).
I have attached the kernel log. I also note that I don't know why the 'PTHERM'
events would be occurring - this was while the connected monitor was off and I
was only connected remotely via SSH.

I will try to add the printk. The lock has made the machine inaccessible remotely, so it'll be a couple of days until I can post the results. -- You are receiving this mail because: You are the assignee for the bug.
