Kernel.log

Hello

First try with suspend2ram with nouveau and kms on my nv30 (Quadro FX 1000). It
fails to restore video modes on resume. The monitor stays off (no signal).
Kernel from nouveau/linux-2.6 git repo, commit
7659293cd9b074f2cf06d68f2d2dd507155162eb (2009-11-24 15:56)

Suspend was done with this, from a text console:
echo mem > /sys/power/state

The kernel log does not show any problem.

However I tried previously from X (KDE 4 has suspend2ram menu item), and on
resume I got a GPU lockup message in kernel log.

Just tried again with current git, still no luck.

Running 'vbetool post' blindly just got me back to 80x25 text mode, with
blinking cursor on the top left; no text content or video mode change.

Starting kdm blindly still triggers the GPU lockup.

With current git of nouveau/linux-2.6, suspend and resume from ram work ok, as
long as X is not running (i.e. only text mode).

As this NV30 card may be currently dying, I don't think I'll ever use it
again,
so I close this bug.
