Hi Daniel, any advice what else to grab besides /sys/kernel/debug/dri/0/i915_error_state and dmesg? after the crash resulting in the forcewake warning (X was gone and I had a completely black screen, had to ssh from a remote machine) the i915_error_state was empty (i.e. no error state collected). Still waiting for the next hang ;). I'll post more debug info asap.
Thx and regards, Dieter -----Ursprüngliche Nachricht----- Von: "Daniel Vetter" <dan...@ffwll.ch> Gesendet: Oct 13, 2011 6:24:34 PM An: "Dieter Mummenschanz" <mummensch...@gmx.net> Betreff: Re: [Intel-gfx] frequent x crashes with gen6/sna >The attached log shouldn't result in a dead X server - it's the rather >harmless forcewake warning when reading certain debugfs files.
