[Bug 50170] kernel 2.6.15-25-k7 smp version crashes after few minutes use

[digimars]

Public bug reported:

I have Ubuntu Dapper Drake 6.06 (with all of the updates that come
across) installed on a machine with an AMD X2 4400+ dual core processor.
I downloaded and installed all of the packages (the kernel image file,
restricted modules, etc.) from the Synaptic package manager and I later
did it again through sudo apt-get.

I can boot into the 2.6.15-25-k7 kernel setup fine after I first
installed this kernel.  The computer ran fine for about 2-5 minutes when
I tried to access another page in firefox when the whole computer locked
up.  I couldn't move my mouse, keyboard input was non-existent, and
there was no activity on my hdd light.

I hard rebooted by the power switch on my tower, and tried again.  This
time, again after about 2-5 minutes of use, I clicked on the window
title bar for my terminal window, and again the computer locked up.  I
hard rebooted again.

Thinking that maybe my mouse was causing this, this time when I logged
in, I brought up a terminal and waited a few moments.  Then, without
moving my mouse, I typed in glxgears into the terminal then hit enter,
then the computer locked up again.

Thinking there was something wrong with this kernel altogether, I tried
to download and install the previous (2.6.15-23-k7) kernel, along with
the smp packages as I had before, however, It would not let me have
anything else specific to the -23 kernel, everything was updated for the
-25 kernel.  So when I tried to boot into that one, X failed to start
because the restricted modules would not configure for the -23 kernel,
only the -25 one.

I did a memtest on my machine, and it passed both full tests that I ran
it through (2GB DDR2 memory).

I am currently working out of a 386 kernel, but I much prefer to have
both of my cores on my processor working.
