For the record, this is commit a8a4f0467d70 ("drm/i915: Fix CFI violations in gt_sysfs") in mainline. > Do you think it can be backported to stable releases ? > Conflicts are trivial on top of v6.0 at least. I had a report from another user of this crash affecting them with kCFI so it is on my TODO to backport it to 6.1 (6.0 just went EOL) but I am currently out of the office until next Wednesday so I won't be able to get to it until then (as I would like to test the backport on affected hardware). If someone wants to beat me to it, I won't complain ;) Cheers, Nathan
