crashdump "watchdog timeout" - Howto get useful information?

[Peter Much]

Dear all,

could anybody share some insight (or pointers to docs) on how to
approach an analysis of a "watchdog timeout" crashdump?

I hopefully have the necessities in place  (that is, I can load
the dump into ddd and actually see things).

But I have no real idea about where to start looking for interesting
things - some structure from where to unroll what the system was
doing (or not doing).
The "developers handbook" mainly explains about figuring the cause 
of the crash - but in my case this is obvious, it is the watchdog I 
have configured.

Since this is a reproducible issue, ideas on things that could be 
configured beforehand could also be useful.

rgds,
