I am affected by the underlying AMDGPU/TTM hibernate-resume issue on Ubuntu 26.04 on an ASUS TUF Gaming A15 FA506NCG.
The failure can result in list corruption / kernel freeze or panic after hibernate-resume, involving TTM/AMDGPU paths such as `ttm_resource_move_to_lru_tail()` and `amdgpu_cs_submit()`. The upstream fix has already been accepted and released in a stable Linux kernel, while Ubuntu 26.04 continues to use the affected 7.0 kernel series and therefore requires the backport tracked by this bug. This is a production machine, so I cannot reasonably test RC, mainline, custom-patched or proposed kernels. I am intentionally remaining on the last known-working Ubuntu kernel until the fix is available through an official stable Ubuntu update. Could the Ubuntu Kernel Team please triage this bug and evaluate the proposed backport for an upcoming Resolute kernel SRU?
