--- Comment #25 from Harald Judt (h.j...@gmx.at) --- Created attachment 301298 --> https://bugzilla.kernel.org/attachment.cgi?id=301298&action=edit dmesg.out I report success, partly. Setting amdgpu.dc=0 on the kernel command line also exhibits the behaviour => Screen suspended, comes back after a while, goes blank again (but powered on), also keyboard back for sysreq, but ssh unresponsive. After applying patch 4 and setting amdgpu.dc=0, the system restores again, but not smoothly. Screen suspends, comes back after a while, also keyboard, display switches back on, machine is responsive and I could generate a dmesg which shows that there have been test failures. dmesg.out attached, but the relevant messages are these: amdgpu 0000:01:00.0: [drm:amdgpu_ib_ring_tests] *ERROR* IB test failed on sdma0 (-110). [drm:process_one_work] *ERROR* ib ring test failed (-110). -- You may reply to this email to add a comment. You are receiving this mail because: You are watching the assignee of the bug.
