PROBLEM: [1.] X session randomly crashes because of kernel problem.

PROBLEM: [1.] X session randomly crashes because of kernel problem.

[Stephane Brossier]

[1.] X session randomly crashes because of kernel problem.

[2.] I installed the standart version of Mandrake8.0,
     and I am working under kde2.1.1 with Xfree86 4.0.3.

     Suddenly my X session exits. Looking at the syslog
     I can see the following log:

Can you duplicate the problem with a more recent kernel, and also 
preferably one without the supermount patch ?

Also does the machine past memtest86 ?

Alan,

Thanks you for your time.

Below are my answers.

I did not try that yet since I need this machine-- and this patch
to work form home. My plan is to update both my hardware and my
kernel but I wanted to report this bug anyway.

Also I can also experience the same problem but with diffrent
traces in syslog.

I don't know if this is another bug or the same one. The behavior
is the same-- my X server crashes suddenly and the kernel seems to
be in a bad state because sometimes after that the machine reboots.

> Also does the machine past memtest86 ?

I tried that this afternoon and everything seems to be fine on
this side.

Thats an X11 3D error, but the bits before it suggest other problems are
triggering it

There is a patch which fixes problems such as this.  IIRC, it was
included in the upstream Linus kernel somewhere in April or
later.  If you're using XFree86 4.0.3, you'll probably want to
upgrade to a later kernel, or patch it with the r128 patch.  You
can get this patch from:

ftp://people.redhat.com/mharris/patches/linux-r128-drm.patch.bz2

I'd offer to change your mind for you, but I don't have a fresh diaper.

OK. Will try.

Thanks.
