Have you run dumpon and/or savecore? You need to at least run dumpon
*before* the kernel crashes, to tell it what device to dump on; later,
when the machine reboots, you want to run savecore to fetch the coredump,
and store it into /var/crash.
This is all best done by specifying dumpdev in rc.conf. You'll have to
manually run dumpon the first time, before the machine crashes; after
the crash, the rc scripts shall run both dumpon and savecore, because
the dumpdev setting in rc.conf tells them to.
G'luck,
Peter
