Arch Linux / CachyOS both normal kernel 6.14.7-5-cachyos (and LTS)
Trying to debug with a minimal kernel command line:
root=LABEL=root resume=PARTLABEL=swap amdgpu.dcdebugmask=0x10 no_console_suspend initrd=amd-ucode.img initrd=initramfs-linux-cachyos.img
The error is coming from the TTM allocator in the AMD GPU:

I tried LTS, tried X11, tried Weston etc… no dice.
Anybody have a workaround?
