Nouveau - Mar 2013 - Fwd: [bisected] nouveau failure with 3.9-rc1 and ongoing

Hiya,

I sent the enclosed email to linux-kernel before realizing that it 
would, perhaps, be more proper to send it here, which I hereby do.

I shall be happy to try out any and all patches.

Best regards,

Sune M?lgaard

Hiya,

Between 3.8 and 3.9-rc1, the following occurs:

Upon boot, when KMS kicks in, I get a blank screen. Keyboard responds
correctly to "Num Lock" on/off, but machine is unreachable on the
network.

Git bisection says:

     drm/nv50: initial kms support for off-chip TMDS/DP encoders

     Signed-off-by: Ben Skeggs <bskeggs at redhat.com>

But even though I marked that last bisection kernel good (since it
didn't cause a black-out), it does have problems, namely that GTK themes
are reset, and xrandr seems non-functional, inasmuch as my left-ward,
secondary screen now seems to be treated as being situated to the right.
No previous kernel in the bisection exercise caused anything of the like.

I'd be happy to try out any and all patches proposed, and as for the
physical card, this is the relevant part:

02:00.0 VGA compatible controller: NVIDIA Corporation G92 [GeForce 9800
GT] (rev a2)

Please let me know if there is anything else I can do to help resolve this!

Best regards,

Sune M?lgaard

I think it may be already fixed by commit
94f54f5336aac6801f2a14dcb12467e41b35456a
"drm/nv50: encoder creation failure doesn't mean full init
failure" (post 3.9-rc2)

Not sure about this one...
