Subjectkernel crashes with 2.5/2.8
Hello everyone,

I've been experiencing (seemingly) random kernel Oops with various
versions of 2.5 and 2.8 on a Dell Poweredge 2650. The machine is
configured with 2GB of ram, a 5GB swap file and two 2.8GHZ Xeons. It
is a NIS/NFS server with an internal hardware raid 5 array on the
Dell Perc card, using the aacraid driver. The RAID5 array comes out
to about 500GB and is where all our user data is stored for NIS users.
That data and the NIS information is accessed by a variety of older
and newer Linux and Sun boxes.

Here is the latest oops from my klog, which happened about a week ago:

I've gotten crashes like this with both 2.5 and 2.8. I'm sorry I
don't have a copy of an oops from the 2.5 crashes. The kermel I'm
using is the stock Fedora Core 2 2.6.8-1.521smp. I've also compiled
my own kernels, various versions from 2.5 - 2.9, but NFS never works
quite right with my kernels. That's even when I'm using the exact
config file that comes with the feodra kernel rpm's. The NFs problems
when I compile my own kernel are inter-operability issues with our
Sun's and other, older, Linux boxes. With the RPM kernels NFS works
great but the crashes are really messings us up, and scaring me about
potential data loss!

Here is a list of loaded modules:

Does anyone have any idea what is causing the panics? I appreciate
any feedback. Is it possible this is a bug within some of the patches
that Fedora is using? I was hopeful going from 2.5 to 2.8 would fix
the issue. Since it didn't I haven't yet jumped to 2.9 but am
planning on doing it tonight.
