Including INVARIANTS stops my kernel from building. It
has been this way since 8.0 (this is why I only
had WITNESS compiled in). It fails with many many
errors like this:
/usr/src/sys/vm/vm_map.c:575: undefined reference to `_mtx_assert'
My kernel config file looks like this:
include GENERIC
ident WITNESS
options KDB
options DDB
options WITNESS
options INVARIANTS

Having read the manual page for textdump, I am not sure I
will be able to get a dump out of this machine, as it has no
swap configured (and no spare partition that I can
allocate for such a thing). I have tried using dumpon
to dump to a ZVOL, but it gives me an error saying
that it is not supported. Is there anything I can do
to remedy this ?

That's fine - this machine is more or less dedicated as a
test ,machine for 8.0 right now. I can possibly dive you console
access to it fi required in fact, as I did this for Robert
once to sort out a problem with 7.0
I'll try running with the current KDB and DDB kernel until
I can figure out how to get a WITNESS/INVARIANTS one built,
and will let you know when that deadlocks.
cheers,
