[skl] HANG: ecode 9:1:85dffffb, in Xorg / 5.8.0-2-amd64 (Debian 5.8.10-1)
On debian unstable, I occasionally get GPU hangs when running certain applications. It's very intermittent (once in a few weeks on average); seems to usually happen when running libreoffice, maybe also chrome. It's been going on for at least many months, over many kernel versions. I suspect I may have faulty hardware, because what happens more often (though still rarely) is a sudden reboot with absolutely no signs of anything in the logs. The latter seems to mostly happen while video conferencing (Skype, Zoom) or sometime playing video in Chrome. I'm not sure whether or not it's related to the GPU hangs. It seems the hangs only happen when running libreoffice or chrome, and the reboots only when playing video, but only in the applications mentioned above (e.g., I don't think it has ever happened while playing a video via mpv).
