Oct 27 22:57:23 Bell kernel: [14133.284499] drm/i915: Resetting chip after gpu
hang
I've added the file where kernel saved crash details,
/sys/class/drm/card0/error.
This is my first bug report, so if more infos are needed, please tell me how to
do, i mean, if there is a script or i have to do it manually.
Thanks.
