AI analysis: A second full freeze occurred at 2026-10-07 11:15:41 PDT on kernel 7.0.0-34-generic. Kernel list debugging reported both list_add corruption and list_del corruption in the TTM resource-manager/LRU eviction path. The triggering process was a browser GPU process, but the call trace is ttm_resource_manager_next → ttm_lru_walk_for_evict → ttm_bo_alloc_resource → amdgpu_cs_bo_validate → amdgpu_cs_ioctl. This is consistent with the prior day’s AMDGPU/TTM Oops and subsequent desktop lockup.
