Bug ID: 107049
Summary: monitor not found in 4.17+ kernel
Product: DRI
Version: unspecified
Hardware: PowerPC
OS: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: DRM/AMDgpu
Assignee: dri-devel@lists.freedesktop.org
Reporter: d...@danny.cz
CC: bcroc...@redhat.com
When booting kernel 4.17 or 4.18-pre on Power9 machine with Radeon Pro WX 4100
I get no output on a monitor connected thru DisplayPort, the monitor is not
detected by the driver and a "PowerPlay" error appears in the kernel log. When
booting 4.16 kernel (kernel-4.16.16-300.fc28.ppc64le), all is OK. See attached
dmesg (resp. journalctl -k -b) outputs.
