https://bugzilla.kernel.org/show_bug.cgi?id=199139 --- Comment #18 from Eduard (wirch.eduard@xxxxxxxxx) --- Even after updating to 4.19 release did not solve the problem. I was able to work around it by disabling monitor power management in Xorg settings: Section "Monitor" Identifier "Monitor0" Option "DPMS" "false" EndSection I sill get this error: kernel: [drm:dce110_vblank_set [amdgpu]] *ERROR* Failed to get VBLANK! But it does not repeat every 10s any more, and also my system does not freeze. So I can finally upgrade from 4.14. -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
