Nouveau - Jan 2014 - [Bug 58378] [NV86] Distorted graphics on NVIDIA GeForce 8400M G after upgrade the kernel to 3.7.0 version

--- Comment #80 from Thomas <tomshere at t-online.de> ---
Hello,

I have the same NVIDIA GeForce NVS 130M with the disabled functions.
I checked with nvapeek:
0000154c: 0000009c
00001540: b1010001

uname -a delivers
Linux mobuntu 3.11.0-15-generic #23-Ubuntu SMP Mon Dec 9 18:17:04 UTC 2013
x86_64 x86_64 x86_64 GNU/Linux

I do not have any issues with distorted graphics during normal usage but my
problem is that resume from suspend mode makes X hang.

I also have these errors in dmesg 

[   18.985158] nouveau E[    PBUS][0000:01:00.0] MMIO write of 0x00000000 FAULT
at 0x00fd94
[   18.986213] nouveau E[    PBUS][0000:01:00.0] MMIO write of 0x00000000 FAULT
at 0x103d94
[   19.026027] nouveau E[    PBUS][0000:01:00.0] MMIO write of 0x00000010 FAULT
at 0x10200c

but also

[   18.984164] nouveau E[  PTHERM][0000:01:00.0] unhandled intr 0x00000161

When I use the kernel option nouveau.config=PCRYPT=0 it doesn't eliminate
the
errors and X still hangs when resuming.
I was not sure if I have to set the parameter in quotes.
As you can see I'm not a linux specialist ;)
