So what I observed was (in that order): machine was building a kernel so
was busy, X didn't respond for a couple of seconds (which it should not
do) and I switched to tty8 to see what dmesg says (I am routing dmesg to
tty8).
At that moment it showed the lockup splat and then X restarted showing
me the login prompt again. I'm guessing the X restart was caused by the
GPU reset.
So if I had to guess, maybe pressing Ctrl+Alt+F8 caused the modeset
change and thus reset? Hmm, this is just me guessing with my
non-knowledge about graphics. :)
Thx.
