Bug ID: 108014
Summary: AMD WX4150 - MST is entirely nonfunctional, spams
dmesg with errors
Product: DRI
Version: DRI git
Hardware: Other
OS: All
Status: NEW
Severity: major
Priority: medium
Component: DRM/AMDgpu
Assignee: dri-devel at lists.freedesktop.org
Reporter: lyude at redhat.com
On the HP Zbook I've got here with an AMD WX4150 GPU, DP MST is entirely
nonfunctional. The only part of MST that works is the first modeset. Every
single modeset afterwards fails while spamming this in dmesg:
