            Bug ID: 102840
           Summary: nouveau PGRAPH - ERROR nsource: ILLEGAL_MTHD nstatus:
                    PROTECTION_FAULT
           Product: DRI
           Version: unspecified
          Hardware: x86 (IA32)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/other

Hi !

First I don't really know if my problem is posted at the right place, sorry for
that, but I don't really understand all the categories...

I got some wrong text rendering in console, and some missing graphical object
under X.

I've found some messages in logs such as :
Sep 18 15:39:44 pluton kernel: [  176.941808] [drm] nouveau 0000:01:00.0:
PFIFO_CACHE_ERROR - Ch 3/4 Mthd 0x0000 Data 0x88000004
Sep 18 15:39:44 pluton kernel: [  176.941840] [drm] nouveau 0000:01:00.0:
PGRAPH - ERROR nsource: ILLEGAL_MTHD nstatus: PROTECTION_FAULT
Sep 18 15:39:44 pluton kernel: [  176.941854] [drm] nouveau 0000:01:00.0:
PGRAPH - ch 3 (0x00075000) subc 4 class 0x0000 mthd 0x0180 data 0x00007308

I've found that this bug is old but can't find a solution.

I've tried to install the Nvidia driver, but it freezes at boot, even I made a
/etc/X11/xorg.conf file (with nvidia-xconfig).

I'm running Debian Wheezy (up to date):
uname :
Linux pluton 3.2.0-4-rt-686-pae #1 SMP PREEMPT RT Debian 3.2.89-2 i686
GNU/Linux

Can you help me solve this ?
Please note that english is not my native language, so write as simple as you
can.

Thanks a lot.

Best regards

Philippe

--- Comment #1 from Ilia Mirkin <imirkin-FrUbXkNCsVf2fBVCVOL8/A@public.gmane.org> ---
Nouveau has been rewritten 5 times since kernel 3.2 came out some short 5.5
years ago, both userspace and kernel driver.

Your issue is some kind of problem with binding a class to a subchannel (that
0x8800004 value is not a valid class id). But I have no idea what might cause
it.

Please try with more recent software. You can play with a x86_64 livecd at
https://nouveau.pmoreau.org/ or use your favorite distribution's recent
release.

We are a few French Nouveau developers, so feel free to come to our IRC channel
#nouveau on freenode, if you would rather speak French than English; those
conversations would be held privately, as not everyone speaks French on the
channel.
