I'm trying to debug the following panic.
I can't get a crash dump.
At the DDB prompt, either "boot sync" or "boot dump"
the system prints "Syncing disks: 2" and nothing more.
I've tried:
removing all disks and/or controllers other than
the disk holding the root
removing physical memory so it is 4G < swap space (5G)
unplugging the offending USB device after the panic
running 6.0 release, 6.0 stable, and the snapshot below
The panic and hang are identical for all cases.
Is there something obvious about my configuration which is
causing this?
Alternatively, is the panic known? It's 100% reproduceable.
I'll submit bug reports for both if that's the best approach.
I wanted to try to debug this myself to possibly get a fix
quickly.
thanks
Geoff Steckel
