Description of problem:
I am getting frequent kernel panics on several Dell Optiplex GX260 SF
(small form factor) computers running with 2GB of memory each. I am
currently running Fedora Core 2 with kernel 2.6.6-1.435.i686. I was
getting panics frequently on older versions of the kernel running the
older Fedora Core 1 also.
I am not certain what is causing the panics and really need some
suggestions on how to resolve the problem.
I have taken digital camera pictures of 5 different systems that have
had a panic and I will try to attach them to this bug report.
I do not know what these errors mean or what is causing the panic. I
would really appreciate any suggestions or fixes for this.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.Systems run for awhile but eventually seem to panic.

I'm also having this problem. Some time after using the system
(sometimes even during boot, sometimes it takes 1 hour) it crashes.
If it's in console mode, it displays a message like that one attached
in Additional Comment #4. FC2 didn't used to freeze. The only
critical changes I remember I did to the system was an up2date and a
kernel upgrade (to kernel-smp-2.6.6-1.435.2.3.i686.rpm).
But i've already tried to downgrade the kernel to FC2 default (in
CD1) and the system is still unstable. I'll reinstall the system and
update it again and pay attention to every change I make and the
effects it causes on the system.
Can someone familiar with the kernel panic messages give an idea what
these panics below are attributed to? I have seen no updates on this
bug nor any suggestions.
The latest Fedora Core 2 kernel 2.6.7-1.494.2.2 still has kernel
panic issues with these Dell Optiplex GX260 small form factor PCs.
Further testing is showing that Redhat Enterprise 3 with kernel
2.4.21-15.0.4.EL is stable so far (last 2 days) on 12 of the GX260
PCs. To me, this is pointing to a kernel issue with Fedora Core 2.
I can add more screen shots if this will help, but it looks like no
one is really looking into this problem so far, so it doesn't seem to
We have resolved these kernel panics. It appears we had incompatible
memory in these Dell Optiplex GX260s. We replaced all the memory,
and the kernel panic problems seem to have gone away. We have not
had any panics since the memory was replaced (4 days now). In case
anyone else gets a lot of panics, try replacing the memory.
