+## Known issues
+
+- **Fixed in builds ≥ `7.1.2_git20260814`**: intermittent GPU wedge under
+  bursty use (e.g. browser scrolling) — `a6xx_gmu_resume: GMU firmware
+  initialization timed out` followed by a hangcheck/recovery storm, sometimes
+  taking the session down. The kernel skipped the GPU's RPMh sleep sequence
+  on every GPU suspend (stale power votes broke a later GPU wake); fix
+  carried from upstream ("drm/msm/a6xx: Fix stale rpmh votes after suspend",
+  currently in drm-msm `msm-next`). Occasional
+  `delay in fenced register write (0x8c1)` lines are unrelated and harmless.
