My main worry is if the retimer scan is the reason for the DPIA issues too.= =20 The report that Sean linked in was a failing to read an EDID which got fixe= d by pushing the scan later. So if you can reproduce the display issues try with it commented out entire= ly (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 microco= de issue. We can talk about that on a drm/amd Gitlab issue. > Now, this is something outside of what software can fix.
