dmesg output on this machine, before suspend

Hi, I'm using nouveau (kernel built today from git, xf86-driver and libdrm
from
at most yesterday, and the rest of the X stack from debian unstable) on my ASUS
laptop.

When going to suspend mode, screens will turn black, and the kernel will just
hang.

Using no_console_suspend altogether with netconsole and dmesg -n8, I can get?:
[  384.372595] PM: Syncing filesystems ... done.
[  384.425291] Freezing user space processes ... (elapsed 0.00 seconds) done.
[  384.426317] Freezing remaining freezable tasks ... (elapsed 0.00 seconds)
done.
[  386.029083] sdhci-pci 0000:06:00.1: PME# disabled
[  386.029118] sdhci-pci 0000:06:00.1: PCI INT B disabled

Then, I get lot of TTM output, something like "Buffer eviction
failed", but it
isn't sent to the netconsole.

Here are info about my card:
01:00.0 VGA compatible controller: nVidia Corporation G73 [GeForce Go 7600]
(rev a1)
01:00.0 0300: 10de:0398 (rev a1)

It's not going to help for your suspend failing, but you're also going
to need
to load the nouveau module with "vbios=PRAMIN" so resume has a chance
of
working, as the PCI ROM image appears useless.

Can you retry with latest git?

Yeah, same thing: a lot of TTM Buffer eviction failed

Now, suspend works fine.
Resuming works, as you said, only if I append nouveau.vbios=PRAMIN to the
kernel boot line (otherwise, the display is extremly corrupted when resuming).
