After applying 2a0158925fb9 ("drm/i915/gem: Prevent overstepping exec array boundary") and verifying the loaded module, VAAPI decode/scale/H.264 encode and full video analyses completed. The previous Oops did not recur and no new kernel/GPU error was detected in these runs. Please carry this already accepted fix into mainline and the affected stable/LTS branches, particularly 6.12. I see it already has Cc: stable #5.10+. AI assistance was used for log/source analysis, test automation and drafting; the reported tests ran on actual hardware. Thanks.
