Check your system logs. Look for logs modified shortly before the
crash. Booting single-user following crash may help preserve
timestamps.
Read /usr/src/linux/REPORTING-BUGS
There are known incmpatibilities with several recent 2.2.x kernels and
various drivers. REPORTING-BUGS identifies most pertinant data. I've
attached a script for automating data collection. It requires ksymoops
somewhere on your path. You may want to tweak it for your own
preferences. You can (and probably should) provide additional
information after the report is generated.
Check your hardware. Bad memory, disks, and CPU are frequent culprits.
Get a memory tester, run badblocks, or try some long compiles and look
for signal-11 errors.

# [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.
