I just didn't get a dump this morning. :-( d130(9.3)[1] grep dump /S4/etc/rc.conf dumpdev="AUTO" d130(9.3)[2] > Just for the record, the easiest way to make iwn firmware panic > is to enter ddb (ctrl-alt-esc), wait five seconds and exit it > ("c<enter>"). Does that process yield useful information? (That is, is that process sufficiently similar to a sequence of events that occurs in the real world that the resulting information may be used to figure out how to make the code avoid misbehavior?) If so, I can try that soonish (e.g., en route home today, once I've boarded the train -- vs. while I'm still on my bike :-}). Peace, david -- David H.
