14:41pabs3: is it useful to report info from GPU hangs? I just had a GPU hang with 4.19.37 and had to reboot https://paste.debian.net/1091908/
15:07karolherbst: pabs3: yeah... I know what's causing the issue and I have some ideas on how to change it... if you are able to ssh into the machine, you can just kill the process and continue
15:07karolherbst: sadly you wouldn't know which process :/
15:08pabs3: I sshed in to reboot, but don't have a key setup for process killing yet
15:08pabs3: I'm guessing a video player might be the likely culprit? or maybe gnome-shell?
15:09karolherbst: applications using the GPU the most are probably the case
15:10pabs3: if it happens again is there any debug/etc info I should gather?
15:10karolherbst: pabs3: my plan was to check inside mesa if such a case happens and just bail out... sadly it requires kernel changes
15:11pabs3: (I usually go quite a long time between hangs)
15:11karolherbst: pabs3: mhhh, I don't think there is much you could actually help out with instead trying to figure out what application is causing it
15:11karolherbst: and try to make it reproducible
15:12pabs3: so if I kill some plausible-culprit processes and guess the right one, the hang will resolve itself?
15:12pabs3: oh, nice.
15:12karolherbst: I think it's some X stupidity waiting on something
15:12karolherbst: but I never really looked into it
15:13karolherbst: or the window manager
15:13karolherbst: or something
15:13pabs3: I noticed that the other hangs I had were with the totem video player playing a video. I'm using GNOME with Xorg
15:13pabs3: this one was the same
