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, PMc
