Also, it was running with dpm=1 aspm=0 now, but disabling dpm (or removing all options, which should be the same) doesn't help a bit. ASPM option was tried just in case.
One last thing: everything seems okay at login screen, but not before and after, and from logs it looks like GPU is resetting successfully. Also, consoles work.
Might be a duplicate of bug 69983. Does reverting to an older version of mesa fix the issue?
Yes, reverting to 9.1.3 (from Ubuntu repos) solves the issue.
Oh, but I have not tried this with new kernel. I'll do this later, and if I have enough time today, I'll try to bisect the bug.
Yes, reverting only Mesa to the old version solves the issue. Later I'll try bisecting this. Sorry for a long break, haven't had enough time.
The computer in question was overheating while building Mesa. I've fixed it today, and with new Mesa from git everything is working properly.
