Do I assume correctly that this still happens with the latest kernel? If so, please try the following things (individually) and let me know if there's any improvement: nouveau.vram_pushbuf=1 nouveau.agpmode=0 Oh, also looking at your log, it looks like you actually have the NV1A, not NV11. (In reply to comment #1) > Do I assume correctly that this still happens with the latest kernel? Impossible to tell with current kernels (3.8.2, 3.10.7, 3.11-rc6) as VGA output is not being lit up properly by nouveau (monitor says "no signal"). See also bug #26534, comments 18 and 20. Created attachment 84758 [details] [review] patch to treat nv1a as pre-nv17 Generationally, NV1A is pre-NV17. However in a bunch of places in the nouveau code, this wasn't recognized. I believe this patch should help, at least with something. Mind trying it out? Should apply on top of a git-ish kernel (but probably doesn't really matter).

Tested-by: Bruno Prémont <bonbons@linux-vserver.org> Could you also retest your various bugs with that patch applied to see if they've resolved themselves? (Including this one.) Created attachment 85214 [details] [review] add nv11 card type Created attachment 85215 [details] [review] fix nv1a chipset checks can you test with the two patches i just uploaded instead? (In reply to comment #8) > Created attachment 85215 [details] [review] [review] > fix nv1a chipset checks > > can you test with the two patches i just uploaded instead? These two patches get the output reaching monitor as well as the previous patch. Note: with nouveau loaded (3.11-rc7, previous patch applied) I had memory (SLAB) corruption as if someone did reuse stale pointers or write beyond allocated memory. I have no idea on the responsible party though they don't seem to happen with VGA console (nouveau not loaded). The scrolling bug seems fixed though. These patches (well, fixed up versions that actually work for nv11+ correctly) are now in nouveau/master. As for the memory corruption issue, try using SLUB with slub_debug=FZPU, that might help figure out what's going wrong. If you find anything concrete, file a new issue. |
