According to Chris this may be a resurgence of Bug 108315. Mika, before I reopen that one can you take a look and see if you agree? Also, these patches may help with this issue so they should be looked at https://patchwork.freedesktop.org/patch/296616/?series=59083&rev=1
There has been also BIOS updates for shards that should improve stability.
The impact of this bug is that a panic can occur on high load and the probability of this panic is very low as this failure is seen only once. Setting the priority to Medium.
Applied Mika's patches to increase CSB size that should put us on an equal footing with HW validation paths... commit 632c7ad6f4509767fcbe76ac034747b4a30a13d9 (HEAD -> drm-intel-next-queued, drm-intel/for-linux-next, drm-intel/drm-intel-next-queued) Author: Mika Kuoppala <mika.kuoppala@linux.intel.com> Date: Fri Apr 5 21:46:57 2019 +0100 drm/i915/icl: Switch to using 12 deep CSB status FIFO Now when we can support variable csb fifo sizes, disable legacy mode. By disabling legacy we hope to get better hw testing coverage by assuming everyone else have switched over. v2: rebase References: https://bugs.freedesktop.org/show_bug.cgi?id=110338 Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Cc: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Cc: Kelvin Gardiner <kelvin.gardiner@intel.com> Cc: Paulo Zanoni <paulo.r.zanoni@intel.com> Signed-off-by: Mika Kuoppala <mika.kuoppala@linux.intel.com> Acked-by: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Link: https://patchwork.freedesktop.org/patch/msgid/20190405204657.12887-2-chris@chris-wilson.co.uk * fingers crossed.
