First "kernel rejected pushbuf" error in log file

Kernel: Linux 4.3 (snapshot from 2015-11-04)
Mesa: 11.0.2
nouveau X11 driver: 1.0.11
Platform: Sony VPCF12S1E with NVidiaGT216M (GForce GT 330M)
System: Debian testing based

Starting the game works fine (although it is somewhat slower than with NVid=
ia's
driver), but once you launch the actual game Unity starts logging up to 1GB=
/min
worth of "kernel rejected pushbuf" logs into the
"~/.config/unity3d/Hinterland/The Long Dark/Player.log" log file.=
 Making that
file (and it's containing directory) read-only I could verify that the game
runs at acceptable frame rates and without noticeable glitches most of the
time. Sometimes however, some textures disappear and it hangs for several
seconds before resuming.

Steps to reproduce:

 1) Purchase and download "The Long Dark" from Steam[1]
 2) Navigate to "~/.local/share/Steam/steamapps/common/TheLongDark&quo=
t; (on the
console or a file browser)
 3) Launch the "tld.x86_64" file[2]
 4) Press any key to move past the disclaimer screen
 5) Select "Sandbox" from the main menu[3]
 6) Start a "New" game or "Continue" a previous surviva=
l trip
 7) Wait for the actual game to load
 8) Observe extreme slowness while the disk I/O is a 100%

"Step 8" does not happen with NVidia binary drivers and the game =
is quite
playable.

See "Player.log.head" for first "kernel rejected pushbuf&quo=
t; error.
The corresponding `dmesg` message is:

    nouveau 0000:01:00.0: tld.x86_64[28285]: nv50cal_space: -16

If you tell me what to do for debugging this, I'll definitely help as much =
as I
can in fixing this issue!
(Including kernel patches, traces, etc.)

Notes:
 1. I'm willing to donate a copy of the game to one established Nouveau
contributor
 2. The game cannot be launched from Steam when using recent versions of Op=
en
source drivers due to https://github.com/ValveSoftware/steam-runtime/issues/34
 3. Due to the game being alpha right now the "Story"-mode has no=
t been
released yet =E2=80=93 this shouldn't matter however
