--- Comment #31 from Hin-Tak Leung <htl10 at users.sourceforge.net> --- Apparently according to the log, I had a GPU crash on 1st March on suspend, which I did not notice. With kernel 3.18.9-200.fc21.x86_64, besides GPU lock up, the kernel also oops'ed. May it is a good thing? : Mar 17 00:35:43 localhost kernel: [12172.039701] WARNING: CPU: 1 PID: 1938 at drivers/gpu/drm/radeon/radeon_object.c:84 radeon_ttm_bo_destroy+ 0xf1/0x100 [radeon]() ...
