Could you check the kernel in OBS home:tiwai:bsc1209436 repo? http://download.opensuse.org/repositories/home:/tiwai:/bsc1209436/pool/
It seems that a backport of i915 upstream fix caused the problem. The kernel above reverted it on top of the latest SLE15-SP4 git branch.
Looking at https://patchwork.freedesktop.org/series/114080/, I see that there are two patches in the series; reading the comments for patch #2, it looks like the two patches need to be applied as a pair. Is it possible the bug was caused by a missing patch #1 (drm/i915: Don't use stolen memory for ring buffers with LLC)? -- You are receiving this mail because: You are on the CC list for the bug.
