https://bugzilla.kernel.org/show_bug.cgi?id=211425 Andreas (icedragon.aw@xxxxxx) changed: What |Removed |Added ---------------------------------------------------------------------------- Kernel Version|5.11.5 |5.11.11 --- Comment #13 from Andreas (icedragon.aw@xxxxxx) --- I have make a comparison with a second full AMD System: A) Ryzen 7 PRO 4750G APU (with build in Vega20) - Renoir B) Ryzen Threadripper 1900X with dedicated Vega64 GPU Both systems have installed the same OS (Kubuntu 20.10 with latest updates), same Xorg configuration (because both have a Vega-GPU), same User IO (monitor, keyboard and mouse) and running with the same mainline Kernel 5.11.11 (similar .config file). - Only my System A) is reproducible infected with the atombios errors (see comments above) and with the two times monitor blackout of each 20sec - after triggering the issue with simple putting the monitor off and on again (after waiting some seconds). - Because both systems have a vega gpu and using the same driver - it seem to be a Renoir APU only problem. - I also observed, that the issue can not be triggered (or is very hard to reproduce) during the sddm login screen! It seems to be, that only a regular KDE user or root session (inclusive the lock screen from a session) is affected by the issue. -> What is the difference? The usage of opengl or other 3d accelerations? I'm also tested with switching the rendering during a session, but I could not observe any difference whatever I used (opengl 2.0, 3.2 or xrendering). >From now I'll only update the bug header for the latest tested (released) kernel version/subversion. -- You may reply to this email to add a comment.
