hi there, Dec 15 22:34:09 amaaq /bsd: inteldrm0: gpu hung!
i have encountered this fellow for the first time so far. when the desktop itself becomes the wallpaper :] googling a bit around i see that there are numerous linux bug reports about similar issues as well. https://bugzilla.redhat.com/show_bug.cgi?id=649860 http://bugs.freedesktop.org/show_bug.cgi?id=25475 http://www.pubbs.net/201003/kernel/58672-regresion-2634-rc1-drmi915hangcheckelapsed-error-hangcheck-timer-elapsed-gpu-hung.html http://cvs.openbsd.org/cgi-bin/query-pr-wrapper?full=yes&numbers=6503 or (looks like same) http://cvs.openbsd.org/cgi-bin/query-pr-wrapper?full=yes&numbers=6505 looking at the source in sys/dev/pci/drm/i915_drv.c:4410 it seems to me that this state is actually anticipated at times, even twice in a row :] as there in no panic(), i guess it is also expected that the hw gets itself together and the system continues working? what does it mean if it doesn't? is there a way to fix it?
