I can trigger a kernel crash on my system by simply loading this png image with firefox: http://mediaarchive.cern.ch/MediaArchive/Photo/Public/2010/1011251/1011251_0...
Sorry the above link is wrong, this is the right one (that triggers the crash): http://cdsweb.cern.ch/record/1305179/files/HI-150431-630470-huge.png
I triggered it a few more times and took the attached picture. It points to the BUG() call at drivers/gpu/drm/ttm/ttm_bo.c:1628 . (Sorry for the bad picture quality)
And here the same BUG in plaintext (should be a bit easier to read):
Nov 8 19:28:23 arch kernel: ------------[ cut here ]------------ Nov 8 19:28:23 arch kernel: kernel BUG at drivers/gpu/drm/ttm/ttm_bo.c:1628!
Quite puzzling it is as if there was already a bo at same offset in rb tree but not in vm mm. Maybe some other race in destruction...
