Hey. The offending patch is apparently: drm/i915/gen8+: Add RC6 CTX corruption WA which is contained in: $ git log --oneline --all | grep "drm/i915/gen8+: Add RC6 CTX corruption WA" 5013e6d917ac drm/i915/gen8+: Add RC6 CTX corruption WA 2248a28384fe drm/i915/gen8+: Add RC6 CTX corruption WA d4360736a7c0 drm/i915/gen8+: Add RC6 CTX corruption WA 255ed51599de drm/i915/gen8+: Add RC6 CTX corruption WA 1a5a64e0bde8 drm/i915/gen8+: Add RC6 CTX corruption WA 00194ecfb32c drm/i915/gen8+: Add RC6 CTX corruption WA 284d38667f7e drm/i915/gen8+: Add RC6 CTX corruption WA 7e34f4e4aad3 drm/i915/gen8+: Add RC6 CTX corruption WA $ git describe --contains 5013e6d917ac 2248a28384fe d4360736a7c0 255ed51599de 1a5a64e0bde8 00194ecfb32c 284d38667f7e 7e34f4e4aad3 v3.16.77~12 v5.5-rc1~28^2~19 v5.3.11~20 v4.19.84~28 v4.14.154~28 v4.9.201~2 v4.4.201~2 v5.4-rc8~28^2~1 The issue seems to affect *all* the i915/gen8+ GPUs, preventing them to enter sleep states. It seems a patch is available at https://gitlab.freedesktop.org/drm/intel/issues/614 and according to https://gitlab.freedesktop.org/drm/intel/issues/953#note_385488 these seem to be the final versions(?). Apparently it's however kinda stuck to get them in a stable release (not really sure why), so could you possibly cherry pick the patch, since that issue is really a major showstopper for all affected people. Cheers, Chris.
