https://bugs.freedesktop.org/show_bug.cgi?id=103102 --- Comment #12 from Hadrien --- Alex, I applied the changes you attached at kernel.org regarding /drivers/gpu/drm/amd/powerplay/hwmgr/smu7_hwmgr.c to my 4.12.5 kernel (and I kept the line that sets vblank_time_us to 0xffffffff). It fixes the issue. I suspended and resumed my system twice without problem. Good catch! -- You are receiving this mail because: You are the assignee for the bug.
