        <pre>After upgrading to:
Linux svoboda 3.15.1-1-ARCH #1 SMP PREEMPT Tue Jun 17 09:32:20 CEST 2014 x86_64
GNU/Linux

nouveau fails to suspend. The interesting dmesg lines are:
[ 1408.108662] nouveau E[   PDISP][0000:01:00.0][0xc000917c][ffff8804261aab80]
fini: 0xc2071088
[ 1408.108663] nouveau E[   PDISP][0000:01:00.0][0xc000917c][ffff8804261aab80]
failed suspend, -16

I have one output connected, an active DisplayPort -> DVI adapter to drive my
27" 2560x1440 monitor.

The card is a Quadro K2000M (NVE7 GK107).

When I was on linux 3.14 using this adapter, suspend worked, but it would fail
during resume - my display would not come back up, but restarting X would fix
it. Unfortunately, I never captured the dmesg from that. The following two
lines were present, however.
