Here are logs from 3 separate type of boots (actually I had to reboot at least 20 times, because I had a lot of crashes/hangs):
1) USB safemode boot (since the normal USB boot didn't work ~ 5 times) 2) USB normal boot (it worked, don't know why, but I'm not complaining) 3) normal installed boot (could log in to GDM, but was not able to start a terminal. Had to switch to VT3 and back to get something useful from the system. Eventually I logged in via SSH. So I was not able to get glxinfo, hope the glxinfo from "2)" suffices.) ** Attachment added: "20220526_logs.zip" https://bugs.launchpad.net/ubuntu/+source/mesa/+bug/1975566/+attachment/5593151/+files/20220526_logs.zip -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1975566 Title: radeon / amdgpu bad performance or panics To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mesa/+bug/1975566/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
