dmesg, kernel next-20131108 until it froze
Tried the next-20131108 kernel.
Still crashes, but now the GPU softresets, sometimes even 5 or so times in a
row. If it resets multiple times, usually freezes the X server, only the mouse
is moving. Sometimes it resets 1 or 2 times first then the X server is usable
(it resets afterwards out of the blue too sometimes, but the X session isnt
affected).
But if i try to launch TF2 again, it locks the X server and sometimes freezes
the whole computer (logs dont show anything). Most times i was able to reboot
with the sysrq keys.
PS. Weird thing, i once was able to play TF2 with the 3.12 final kernel too.
Then it was perfectly playable, launched it a few times in a row and had no
issues whatsoever. I did nothing out of the ordinary, the session was running
for a day or 2 after which i launched it, previously i compiled stuff, tested
stuff in virtual machines, watched movies, browsed etc.
However after reboot i couldnt reproduce this. No software (mesa etc) was
changed, but after reboot, it crashed as before.
