These still occur in `dmesg`: [78655.572618] amdgpu 0000:04:00.0: [drm] REG_WAIT timeout 1us * 100000 tries - optc1_wait_for_state line:839 [78655.807712] amdgpu 0000:04:00.0: [drm] REG_WAIT timeout 1us * 100000 tries - optc1_wait_for_state line:839 [78656.042603] amdgpu 0000:04:00.0: [drm] REG_WAIT timeout 1us * 100000 tries - optc1_wait_for_state line:839 [78668.627927] workqueue: dm_irq_work_func [amdgpu] hogged CPU for >10000us 8 times, consider switching to WQ_UNBOUND [78670.615140] audit: type=1326 audit(1743681500.198:707): auid=1000 uid=1000 gid=1000 ses=3 subj=snap.slack.slack pid=6457 comm="slack" exe="/snap/slack/194/usr/lib/slack/slack" sig=0 arch=c000003e syscall=92 compat=0 ip=0x7bf758d0458b code=0x50000 [78670.897942] [drm:parse_edid_cea_dmub.constprop.0 [amdgpu]] *ERROR* EDID CEA parser failed [78671.546918] [drm:parse_edid_cea_dmub.constprop.0 [amdgpu]] *ERROR* EDID CEA parser failed Another observation is that switching to textual console (tty3) leaves it sluggish, meaning frame buffer for the console is affected as well. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-amdgpu in Ubuntu. https://bugs.launchpad.net/bugs/2093268 Title: Main screen becomes sluggish after wake up To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-meta-hwe-6.8/+bug/2093268/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
