Comment 2 Alex Buell 2011-01-10 05:32:12 UTC
I'd like to add that I have experienced the same problem with Fedora 15 and Ubuntu Natty with the same hardware. Also, I have a newer laptop with NV34 chipset, the above distributions and Gentoo works perfectly on that.
Comment 3 Alex Buell 2011-01-10 05:40:20 UTC
Is there anything I can do to help get this sorted for the NV11 chipset?
Comment 4 Alex Buell 2011-01-10 06:16:44 UTC
I have some newer logs, with VESA_FB and PRINTK timings enable attached to this report.
Comment 7 Alex Buell 2011-01-11 02:58:58 UTC
Created attachment 41872 [details] dmesg with kernel parameter video=LVDS-1:d added
Comment 8 Alex Buell 2011-01-11 05:47:51 UTC
Just been doing some additional work on this. Apparently disabling LVDS-1 got X working. I am now building 2.6.37 and testing again to see if the fixes applied to that kernel solves the issue entirely.
Comment 9 Alex Buell 2011-01-11 06:23:48 UTC
Ok, 2.6.37 is a total disaster. Booting w/o video=LVDS-1:d resulted in a solid kernel lockup. Not able to ssh in and look for myself what was wrong. Booting /w video=LVDS-1:d, resulted in a booting 2.6.37 kernel, looks OK but X wouldn't start.

Comment 12 Marcin Slusarz 2011-01-11 08:47:55 UTC
what happens if you remove "vga=791" from 2.6.37 kernel command line?
Comment 13 Alex Buell 2011-01-11 09:39:58 UTC
Makes no real difference,the problem is with X trying to start up but not getting what it needs. Console working perfectly OK. 2.6.37 could not even boot with all vga/video related parameters removed, needed just LVDS-1:-d to even boot. I suspect something has substantially changed for the worse with 2.6.37.
Comment 14 Alex Buell 2011-01-12 02:59:29 UTC
I added a xorg.conf to the 2.6.37 kernel, and got a GPU hang. Eep! Added xorg,conf and relevant logs.

Comment 18 Alex Buell 2011-01-12 04:06:17 UTC
With diff --git a/drivers/gpu/drm/nouveau/nouveau_bo.c b/drivers/gpu/drm/nouveau/nouveau_bo.c index cfb8a3c..97de9e1 100644 (nv10_invalid_placement_range.patch), and same kernel parameter arguments, it boots just fine but X still exhibits problem. New logs added. Next thing to do is to test kernel without these parameters.

Comment 27 Alex Buell 2011-01-31 03:54:47 UTC
At long last. I've managed to get debugging w/ drm.debug=6. Attached is the log output.
Comment 28 Alex Buell 2011-01-31 03:55:27 UTC
Created attachment 42744 [details] drm.debug=6 output via netconsole.
Comment 29 Alex Buell 2011-01-31 14:33:57 UTC
Here's some extra information. Apparently if I add 'video=LVDS:d' to the kernel parameter line, the hang with 2.6.37 doesn't happen. This definitely was not needed with 2.6.36.
Comment 30 Alex Buell 2011-01-31 14:43:29 UTC
Some more experiments w/ the video=LVDS-1:d parameter on 2.6.36 Without creates a 1600x1200 display but console thinks it is 1024x768 With it creates a 1600x1200 display and console thinks it is 1600x1200. I hope this is of use!
Comment 31 Francisco Jerez 2011-02-02 08:38:19 UTC
Created attachment 42858 [details] [review] nv04_lvds_no_native_mode.patch (In reply to comment #29) > Here's some extra information. > > Apparently if I add 'video=LVDS:d' to the kernel parameter line, the hang with > 2.6.37 doesn't happen. This definitely was not needed with 2.6.36. The attached patch should help with that crash. To find out why we can't find a native mode for your LVDS panel, can you get me a BIOS dump?

Comment 34 Alex Buell 2011-02-02 15:37:42 UTC
http://annarchy.freedesktop.org/~currojerez/nv10_invalid_placement_range.patch This patch is also required to prevent X crashes.
Comment 35 Alex Buell 2011-02-02 16:12:56 UTC
Thank you, the two patches given above fixed the problem entirely for me, no more X or kernel hangs with 2.6.37. I now consider this report closed. Until the next time :)
