I am experiencing the *exact* same bug. I'm running Fedora 28 with MATE desktop, so I'm confident this is not a KDE problem. My error message: [39911.150851] [drm:generic_reg_wait [amdgpu]] *ERROR* REG_WAIT timeout 10us * 3000 tries - dce110_stream_encoder_dp_blank line:956 [39911.150927] WARNING: CPU: 5 PID: 1452 at drivers/gpu/drm/amd/amdgpu/../display/dc/dc_helper.c:195 generic_reg_wait+0xe7/0x160 [amdgpu] Mobo: Supermicro X9SRL CPU: intel Xeon E5 2680 v2 GPU: MSI Radeon RX 480 4GB with latest polaris10 bin file Kernel: 4.17.19 Mesa: 18.0.5 This must be an AMDGPU driver bug. I'm also connected via DisplayPort and I frequently get the monitor sleeping to powersave mode during boot. If I switch to TTY1 and do a Ctrl-Alt-Del reboot, it usually boots up normally after the blind "three finger salute" reboot.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
