You can use q4 to analyze the crash. However, the cause will not be what you expect. It might be that an address in memory was misaligned due to a bug in a driver but about all you'll know is the name of the module that caused the error. Virtually all panics are solved with proper patches. Without a detailed analysis of the actual failure you'll not be able to pick a specific patch.

So the easiest approach is to add the current patches. They are in two packages: HWE (to fix or add any hardware features) and Gold QPK. Download both, install HWE ifrst, then QPK. That should eliminate any panics and fix a large number of other problems.

Unless you have access to the code and be familiar with the architecture of Unix to do analysis of a crash is not easy thing. It's better to use the shotgun approach, install all the patches on the Gold QPK and HWE. But there are some tricks that can be used although not supported by HP. Run q4 and include a script called whathappened.pl:

q4> include whathappened.pl
q4> run WhatHappened > w.txt

The output file w.txt will have information about the last ticks of your system. It may not be enough but... Who knows.

Attaching an html q4 procedure.

I always send the results to hp for interpretation. It usually leads to a patch install.-
