Every half an hour or so of especially intensive use, such as switching workspaces a lot or running games/flightgear, I see the screen freeze for a minute, during which everything non-graphics related keeps going -- then mo= st of the time it recovers, but if one hang happens more hangs are likely to o= ccur soon, and sometimes they either start happening without a pause, or perf degrades so bad I have to kill X or reboot the computer. During that minute I can not do anything at all: - switching to console does not work; - if I suspend to reset the video, the whole machine hangs. So I either have to reboot it -- or just wait a whole minute. Might be related to https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D194= 766 but I don't see the same stream of errors, only the "error: [drm:pid12:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU h= ung" and something else. Is there a way to at least make this hangcheck run more often, say, every 10 seconds, so I don't have to just sit there? --=20 You are receiving this mail because: You are the assignee for the bug.=
