Created an attachment (id=73220) --> (https://bugzilla.kernel.org/attachment.cgi?id=73220) 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.
