Repeating system freeze on AMD 7040 (hardware acceleration / VA-API / Display Core related?)

Framework Laptops
1

I’m running Bluefin on a Framework Laptop 13 (AMD 7040 series), and I’ve been experiencing recurring (multiple-times daily) partial-to-total system freezes, most often when playing video in Zen Browser, but sometimes browsing in general. I’m looking for guidance and/or confirmation from others on similar hardware.

Symptoms

  • Issue typically occurs during YouTube or other video playback.
  • Initial freeze affects mouse, power button (e.g. when pressing once to suspend, but holding to power off works), most keyboard input (e.g. the volume up and down buttons work for some reason, at least for a while).
  • I can sometimes pause the video with the space bar briefly while the rest of the UI is frozen.
  • Audio continues for a short time before cutting out completely.
  • After ~20–30 seconds, the entire system becomes unresponsive (no lid action, no power button response). Sometimes screen goes white altogether.
  • Hard shutdown required to recover.

System Details

  • Image: ghcr.io/ublue-os/bluefin-dx:stable
  • Kernel: 6.14.3-300.fc42.x86_64
  • GPU: AMD Radeon 780M (integrated)
  • BIOS: v03.09 (April 2025)
  • Secure Boot: enabled

Relevant Logs

From journalctl and dmesg:

amdgpu ... [CRTC:79:crtc-0] flip_done timed out
amdgpu ... DMCUB error - collecting diagnostic data
systemd-remount-fs.service failed
SELinux is preventing ostree from remount access on the filesystem

These appear every time the freeze occurs.

What I’ve Tried So Far

  • Disabled VA-API and hardware acceleration in Zen Browser.
  • Issue still occurs, but maybe slightly less frequently.
    (currently evaluating).
  • Firmware is fully updated via fwupd.

What I’m Looking For

  • Has anyone else experienced freeze issues on AMD 7040 / Radeon 780M under Bluefin or similar Fedora base?
  • Are there recommended kernels or Mesa versions that avoid this instability?
  • Any known issues with amdgpu.dc=0 in Bluefin or even Fedora Silverblue?
  • Would switching to the LTS kernel be advisable here?
  • ?

Thanks in advance! Super appreciate the work uBlue is doing. Happy to run more diagnostics or try a different image if that helps. Or nuke everything and start over?

We’ll be getting a new kernel on tuesday, not sure if it will help, just pointing it out!

Did you check the Framework forums? There’s this:

It seems to be a bug in the mesa version 25.0.5-1. I am getting the same issues on Aurora with AMD Ryzen 7 8840HS.
