dmesg output after the freeze

My machine froze for a few seconds while playing a WebGL Unity game in web browser (Firefox). I've been playing the game for months without such problem so it's very likely I won't be able to reproduce this. dmesg report, GPU crash dump and X server log are attached.

My system is Gentoo Linux running on HP ProBook 450 (about 2 years old) with Intel Core i5 CPU. The machine also has additional AMD Radeon GPU which I don't use. I had no external displays connected when the freeze happened (only the built-in laptop display was active).

uname -mr: 4.4.2-gentoo x86_64

Comment 3 Chris Wilson 2016-07-21 19:54:23 UTC 
There's nothing unusual in the batch that took the blame either. First thought is along the lines of memory/GTT placement. No testable hypothesis atm.
Comment 4 Jari Tahvanainen 2017-03-08 10:33:29 UTC 
Chris - do you see a relation between this and Bug 88411? Both are for (4.4.x) kernel, other one reported against HSW though...
Comment 5 Jari Tahvanainen 2017-04-10 11:15:16 UTC 
Martin - is problem still valid with the latest kernel version (preferable drm-tip from git://anongit.freedesktop.org/git/drm-tip)? If yes then please change status to REOPENED and attach newest data, like you did originally.
Comment 6 Jari Tahvanainen 2017-05-23 13:19:38 UTC 
Timeout - marking resolved+worksforme. Please reopen the bug if problem still persists with the latest kernels (preferable from drm-tip).
