Public bug reported:
On Ubuntu 26, the desktop froze on an AMD GPU system. The kernel logged a page
fault at ttm_lru_bulk_move_tail+0x1a5/0x360 during amdgpu_vm_move_to_lru_tail /
amdgpu_cs_submit, initially from gnome-text-editor while it was using Vulkan.
After the Oops, gnome-shell repeatedly soft-locked in the AMDGPU/TTM DRM
object-cleanup path (ttm_resource_free, ttm_bo_release, amdgpu_gem_object_free).
