<pre>Alright, I am unable to get a dmesg log after crashes since my system is
completely unresponsive...even to ssh from another machine.
I setup a watch -n 10 of dmesg to dump to file so I'll be able to grab it on
reboot.
I have identified 3 district crash states. All three start the same way,
everything freezes except mouse, then:
- screen will flash once or twice and drop to black screen
- screen will flash once or twice and drop to tty7 (instead of 8) which has
boot log with last message saying (starting X)
- third state it will do the second one, but allow I can switch to another tty
screen as the machine is responsive after that, just x is dead.
The Xorg log differs between the first two states (see attachments): "xorg.log
from crash" (being state one), and "xorg.log closed and dropped to tty" (being
state two).
I have seen the machine be stable for 12+ hours and then die while locked and
displays off, other times it dies after 3-4 min, and others a couple hours. I
cannot find a correlation between what I am doing (or applications open) when
it dies (and the example of being entirely away seems to support that).
Is there some reasonable instructions for performing a git bisect? I am
familiar with all sorts of development, but not a kernel developer. Is it safe
to assume this is in the driver and not Xorg?</pre>
