Hi there, Sometimes my computer crashes since i use now ubuntu 13.10 with unity/compiz. dmesg tells me: [ 686.209019] nouveau E[ PBUS][0000:00:0d.0] MMIO write of 0x00000000 FAULT at 0x00b020 and later: [ 1425.565441] nouveau E[ PGRAPH][0000:00:0d.0] ERROR nsource: DATA_ERROR nstatus: BAD_ARGUMENT [ 1425.565462] nouveau E[ PGRAPH][0000:00:0d.0] ch 3 [0x00056000 compiz[1970]] subc 2 class 0x0039 mthd 0x0314 data 0x031dc000 So I don't really know where to start for debugging, if you could help me that would be great. Full dmesg output on http://ubuntuone.com/3AVhp6HT2jU26HdfguAbdV thanks, Martin

Do you have mesa 9.2.1 or later (or pre-9.2)? If you have 9.2.0, there are known issues with shader compilation.> > dmesg tells me: > > [ 686.209019] nouveau E[ PBUS][0000:00:0d.0] MMIO write of 0x00000000 > FAULT at 0x00b020Odd. That's VPE. You should have one... maybe not. Nothing to worry about though.

A pitch of 50MB... I wonder how that's happening... If you feel like debugging, the place to look is nv30_transfer.c (in mesa). Although I would think this would merely cause misrendering, not crashes.> > So I don't really know where to start for debugging, > if you could help me that would be great. > > Full dmesg output on http://ubuntuone.com/3AVhp6HT2jU26HdfguAbdV > > thanks, > Martin > _______________________________________________ > Nouveau mailing list > Nouveau at lists.freedesktop.org > http://lists.freedesktop.org/mailman/listinfo/nouveau

I also think that this can cause missrendering, and not crashes, but it also seems that there aren't stored any messages on the crash, maybe it crashes before it can write something to the harddisk? But thank you for your help. Martin
