Thanks for filing this report. I'm reassigning to Jesse. Created attachment 18248 [details] [review] don't steal crtcs for detection Mac minis might need this patch to avoid pipe stealing... (In reply to comment #2) > Created an attachment (id=18248) [details] > don't steal crtcs for detection > > Mac minis might need this patch to avoid pipe stealing... I just tested your patch applied on top of and his improved a lot I just got one single flicker when starting firefox. All other apps I tested start cleanly now. commit 2049ba211e7cdc383976c09f52c2b43acdd59481 Author: Jesse Barnes <jbarnes@hobbes.lan> Date: Thu Jul 31 13:07:20 2008 -0700 Update DSPARB while planes are still off This avoids the flickering people reported in the 2.4.0 release. Might this have anything to do with bug #17059 I just tried to reproduce it and it did not crash, this has not happened for a long time. ;) Will have to find some time to try more and then report back.

I don't think this will fix your crash... It would be good if you could get a backtrace though, the logs in that bug don't include anything helpful. You can login remotely and try running gdb on the server. I think the intellinuxgraphics.org site has some info on getting good debug info. Created attachment 18269 [details]

I have been running your don't steal crtc patch the whole day. But now I got a crash:

Probably is more readable as attachment.
Is this a new bug?
I am moving tomorrow therefore I am not sure when I will be able to answer again. Yeah I think that's a new bug, sounds like the stealing avoidance patch fixes things for you in this case... We'll push the fix for 2.5. NAK on this patch to fix this issue. DSPARB setting should be fixed to not turn off all planes when only one's on. Pushed different fix as 5af504166f14f4401818f3b7c27ac2ccba7b9ff5. |
