I > do see MST and that seem to be problematic in Linux IIRC. My main worry is if the retimer scan is the reason for the DPIA issues too. The report that Sean linked in was a failing to read an EDID which got fixed by pushing the scan later. So if you can reproduce the display issues try with it commented out entirely (maybe we want that for debugging as a module parameter Mika?). With it commented out if they're cleared up, I think we still need to push it to a delayed work queue. If they're still happening, then this should be a GPU driver or GPU microcode issue. We can talk about that on a drm/amd Gitlab issue. > Now, this is something outside of what software can fix.
