dmesg output of a cold boot -> suspend to disk > resume cycle

When sending the PC into suspend to disk mode via echo disk > /sys/power/state
or using pm-suspend the resume process fails with the following messages:

[   61.782648] [drm] nouveau 0000:01:00.0: timeout:
URSOR_CTRL2_STATUS_ACTIVE(0)
[   61.782709] [drm] nouveau 0000:01:00.0: CURSOR_CTRL2(0) = 0x00000000

This bug is reproducible on several 3.3.x and 3.4-rc kernels. I did not test it
on prior kernels. Suspend to RAM works fine.

The card used here is a nvce, Gainward 560 Ti, 2G video ram.
