Description
Hi folks,
I have:
01:00.0 VGA compatible controller [0300]: NVIDIA Corporation GK107GLM [Quadro K1000M] [10de:0ffc] (rev a1)
(one year old thinkpad laptop)
and I'm unable to wake up. Well, not be, but my "Linux 3.11-2-amd64 #1 SMP Debian 3.11.8-1 (2013-11-13) x86_64 GNU/Linux" (Mint, Debian Edition, "testing").
Optimus is disabled in BIOS (only discrete is used). On waking up I see four lines:
[ 8618.926501] mei_me 0000:00:16.0: suspend
[ 8623.309085] nouveau E[ PDISP][000:01:00.0] DP:0006:0f48: failed to read DPCD

[ 8625.220712] PM: Device 4-1.8.1.1.1 failed to resume async: error -32
Reproducible only with external monitors (via dock station).
Sorry, not sure how to get Nouveau version.
$ apt-cache showpkg xserver-xorg-video-nouveau
...
Dependencies:
1:1.0.10-1 - libc6 (2 2.15) libdrm-nouveau2 (2 2.4.38) libdrm2 (2 2.4.25) libudev1 (2 183) xorg-video-abi-14 (0 (null)) xserver-xorg-core (2 2:1.13.99.901) libgl1-mesa-dri (2 9.0) xserver-xorg-video-nouveau:i386 (0 (null)) " if that helps.
