Debugging kernel panics is a bit of a black art.

Knowing what kernel you're using helps a bit.

Take a look at the attached script.  It will create a kernel bug report
based on the format suggested in /usr/src/linux/REPORTING-BUGS.  You'll
need to put ksymoops somewhere on your path for it to work.

No promises, but this may provide additional insight.

# ------------------------------------------------------------------------
# [Some of this is taken from Frohwalt Egerer's original linux-kernel FAQ]
# 
#      What follows is a suggested procedure for reporting Linux bugs. You
# aren't obliged to use the bug reporting format, it is provided as a guide
# to the kind of information that can be useful to developers - no more.
# 
#      If the failure includes an "OOPS:" type message in your log or on
# screen please read "Documentation/oops-tracing.txt" before posting your
# bug report. This explains what you should do with the "Oops" information
# to make it useful to the recipient.
# 
#       Send the output the maintainer of the kernel area that seems to
# be involved with the problem. Don't worry too much about getting the
# wrong person. If you are unsure send it to the person responsible for the
# code relevant to what you were doing. If it occurs repeatably try and
# describe how to recreate it. That is worth even more than the oops itself.
# The list of maintainers is in the MAINTAINERS file in this directory.
# 
#       If you are totally stumped as to whom to send the report, send it to
# linux-kernel@vger.rutgers.edu. (For more information on the linux-kernel
# mailing list see http://www.tux.org/lkml/).
# 
# This is a suggested format for a bug report sent to the Linux kernel mailing 
# list. Having a standardized bug report form makes it easier  for you not to 
# overlook things, and easier for the developers to find the pieces of 
# information they're really interested in. Don't feel you have to follow it.
# 
#    First run the ver_linux script included as scripts/ver_linux or
# at <URL:ftp://ftp.sai.msu.su/pub/Linux/ver_linux> It checks out
# the version of some important subsystems.  Run it with the command
# "sh scripts/ver_linux"
# 
# Use that information to fill in all fields of the bug report form, and
# post it to the mailing list with a subject of "PROBLEM: <one line
# summary from [1.]>" for easy identification by the developers    
# ------------------------------------------------------------------------

This is a script-generated kernel bug report.  

The system administrator/developer should provide additional information 
where appropriate.
