Found this post while searching for similar issues. I’m not using a Framework laptop, but I’m seeing very similar behavior.
Hardware:
Ryzen AI 9 HX 370 (Strix Point) with Radeon 890M (gfx1150), 96 GB RAM, Pop!_OS 24.04 (Ubuntu-based), kernel 6.17.x.
Symptoms:
-
Hard system freezes that end in hung_task panic / kernel panic
-
Happens on Wayland (COSMIC & GNOME) and also on Xorg
-
Sometimes the screen fills with purple noise / corruption before crashing
-
After a crash, Wi-Fi and Bluetooth stop working until a full power-off
-
Often triggered by browser usage (PDFs, banking sites, GPU-accelerated content)
-
System logs often stop before the freeze; pstore is usually empty
Debugging done (with help from others):
-
Memory test passed (no RAM errors)
-
Tried disabling panel self refresh (PSR)
-
Tried disabling PCIe power saving (ASPM)
-
Tested multiple desktop setups: GNOME and COSMIC, both Wayland and Xorg
-
Removed ROCm / GPU compute stack
-
Tested different AMD firmware versions (both distro default and newer upstream firmware)
-
Noticed occasional AMD GPU memory/page fault messages early after boot
The crashes still happen intermittently, even on Xorg, which suggests this is not compositor-specific.
This looks very similar to the recent amdgpu DCN / DMUB / Strix Point issues discussed here. I don’t have a solution yet, but I wanted to share my findings in case others run into the same problem.
