Subject: Request: backport 2ee9836545e6 ("drm/amdgpu: Fix VCE 3 ring align_mask") to 6.18.y and 7.2.y
Date: Tue, 20 Oct 2026 20:09:27 +0000	[thread overview]
Message-ID: <18e055c816c88bcf-14970a90@a-workstation> (raw)

Hi,

Please consider 2ee9836545e6 ("drm/amdgpu: Fix VCE 3 ring align_mask") for 6.18.y and 7.2.y. It's tagged for stable but isn't in 6.18.57 or 7.2.11, while both have d5ab4c6a64ef ("drm/amdgpu: Implement insert_end for VCE 3"), which it fixes (6.18 since 6.18.46).

Without it, VA-API encoding on an RX 580 hangs the VCE ring:

  amdgpu: ring vce0 timeout, signaled seq=..., emitted seq=...
  amdgpu: suspend of IP block <vce_v3_0> failed -22

6.18.42 is fine; 6.18.50 hung three times in three days. Someone else sees the same on 7.2.6: https://github.com/rustdesk/rustdesk/issues/16324

The fix is one line and applies to both trees.

Thanks
