Bug#438736: intel driver produces kernel crash in a variety of situations
I've recently upgraded my hardware (motherboard + cpu + ram) and am now
getting Linux crashes in a variety of situations. I've detected them
when any of the following conditions are met:
- When starting a second X session.
- When time goes backwards (e.g. due to ntpdate) while X is running (but
NOT when X isn't running)
- When stopping X.
When this happens, terminal is switched to console, and a kernel backtrace is
displayed. As for the backtrace, I've seen it at least once hitting functions
related to intel driver, but it seems to be completely different every time.
I can get it captured if that's of any use.
Also, sometimes the crash is complete, and sometimes SysReq key responds
allowing for a cleaner reboot.
Some notes on my system:
- Two cpu cores (Could parallelism be an issue? If it's possible to disable
SMP without recompile I could give that a quick try)
- X driver is xserver-xorg-video-i810. Card model:
