I see in the original email: https://lore.kernel.org/stable/3423617.kz1aARBMGD@archlinux/ That Diego is using the iGPU part of a Haswell CPU, so yes this is almost certainly the same issue. Diego as I already mentioned to another arch user, it would be good if the arch kernel-maintainers can pick-up these 3 commits from the drm-intel tree as downstream patches for now: e627d5923cae ("drm/i915/gt: One more flush for Baytrail clear residuals") d30bbd62b1bf ("drm/i915/gt: Flush before changing register state") 1914911f4aa0 ("drm/i915/gt: Correct surface base address for renderclear") We (Fedora) have added these as downstream patches for now and we have multiple reports that these resolve the problem. Chris, can you please send the 2nd and 3th commit of the above list on their way to Linus ASAP, so that Greg can add them to the stable series? ATM only the 1st commit is in Linus tree (unless the others have landed with different hashes?)
