Anyone else with AMD 7040 FW13 and running Fedora 42 and KDE plasma seeing AMD GPU crashes with kernel 6.18.13-100.fc42.x86_64 that weren’t present before? I’ve gotten 2 over the last 3 days whereas before I was mostly stable.

I’m adding amdgpu.dcdebugmask=0x10 since searching suggests tons of problems with PSR and AMD GPU, just weird I never needed it before.
I saw this just once, with Arch Linux kernel 6.18.9 a few days ago. Haven’t seen it before or since (now on kernel 6.18.13).
I’m running Cinnamon desktop on Xorg. It seemed like everything froze, and then after a minute things were just unbearably laggy and unresponsive, but I was able to painfully collect logs and reboot.
Also noticed it on Fedora Silverblue 43 6.18.13-200.fc43.x86_64 on a FW13 AMD7040, I get similar logs:
Feb 23 19:05:31 ... kernel: amdgpu 0000:c1:00.0: [drm] *ERROR* dc_dmub_srv_log_diagnostic_data: DMCUB error - collecting diagnostic data
Feb 23 19:05:31 ... kernel: amdgpu 0000:c1:00.0: [drm] *ERROR* dc_dmub_srv_log_diagnostic_data: DMCUB error - collecting diagnostic data
Feb 23 19:05:41 ... kernel: amdgpu 0000:c1:00.0: [drm] *ERROR* [CRTC:80:crtc-0] flip_done timed out
It started happening recently (not having seen this issue before), and even had it happen twice in one evening. There was another thread on the forum with this same error, naming GNOME Night Light feature as known potential cause for the issue. After turning off Night Light, I haven’t seen the crash anymore (anecdotal, but might help others).
Yeah I just had this happened to me, sucks. I’m on kernel 6.18.10-200.fc43.x86_64 running Bluefin (based on Fedora Silverblue).
It happened a two minutes after the night shift ran at 19:12.

Getting same problem. Running Kubuntu (Ubuntu w/ KDE Plasma) 25.10 on Framework Desktop. System intermittently locks up and requires power down to reboot. Reinstalled Kubuntu on another drive to test. New install seemed stable but has now also locked up once.
System was stable (and great) before this week. I do have a Clonzilla complete image from a couple weeks ago. Have saved all my current development work to an external drive and will try restoring the Clonzilla image if it can’t get this fixed. Reluctant to do this because it will probably take a whole day. Will wait a little while before trying this because there may be a real fix.
Will be really grateful If someone can figure this out. It’s crashing 3 or 4 time a day and it’s interfering with development.
More Info:
When running:
journalctl -b -1 -e
Results include:

Do we need an update to the amdgpu kernal driver?
Is the problem restricted to KDE Plasma?
My second install of Kubuntu is not using the night light feature but has experienced the same bug.
Been running Chrome but will experiment with just using Firefox.
Tried amdgpu.dcdebugmask=0x10 but problem still there.
Intermittent problems are hard to diagnose (and fix). Wish everyone good luck.
Have really liked Kubuntu on Framework Desktop but does anyone have any recommendations for alternatives? Using JetBrains Rider to do C# development in Genetic Programming and generative art.
I believe the problem is caused by an interaction between KDE, AMDGPU drivers and chromium based web browsers. I have switch to using Firefox and have had no problems. Still running KDE (Fedora 43 KDE) and stil running on Framework Desktop.
