:Ack, but what I meant is that syncing actually _works_ with the direct
:panic() call in syscons.c in place of Debugger(). And I get the dump.

:So it looks like there is an issue with DBB and syncing, as syncing

There are a bunch of issues with syncing, the main one being that
it is usually just too dangerous to try to sync the buffers from a
panic or debugger state. I think FreeBSD no longer syncs its buffers
on a panic and we probably should stop doing it too.
