Hi Jesse, I've tried your patch below. It locked up my machine a few seconds after X startup :(. I didn't use any boot parameter. I've changed the parameters during runtime by echoing sysfs.
I've filed a bug under https://bugs.freedesktop.org/show_bug.cgi?id=38529[../../jump.htm?goto=https%3A%2F%2Fbugs.freedesktop.org%2Fshow_bug.cgi%3Fid%3D38529][../../jump.htm?goto=https%3A%2F%2Fbugs.freedesktop.org%2Fshow_bug.cgi%3Fid%3D38529]. Chris Wilson already proposed a patch that solves the stalling and so far my system runs stable even with SNA enabled in xf86-video-intel. However now it seems I'm unable to get my framebuffer console back after I bailed out of X. The screen stays black but my system is still responsive via ssh. This happens without your patch. I'll do some more investigation to make sure I didnt introduce this issue. Thanks and regards, nic -----Ursprüngliche Nachricht----- Von: "Jesse Barnes" <jbar...@virtuousgeek.org> Gesendet: Jun 21, 2011 6:55:27 PM An: "Nicolas Kalkhof" <nkalk...@web.de> Betreff: Re: [Intel-gfx] gen6 (SNB) GPU still stalling besides latest patches >On Tue, 21 Jun 2011 18:12:56 +0200 (CEST) >"Nicolas Kalkhof" <nkalk...@web.de> wrote: > >> Hi Jesse, >> >> thanks for the infiormation.
