Comment 1 Chris Wilson 2019-08-19 14:04:31 UTC
commit 6a736ebf314a0b0813bae248ad3daa9154463798
Author: Chris Wilson <chris@chris-wilson.co.uk>
Date:   Mon Aug 19 08:58:18 2019 +0100

    drm/i915: Always wrap the ring offset before resetting
    
    We were passing in an unwrapped offset into intel_ring_reset() on
    unpinning. Sooner or later that had to land on ring->size.
