7.0-BETA4 - witness_warn on boot

I was running 7.0-BETA4 and had problems with SEG_FAULT 12 in g_up so I
rebuilt a stock GENERIC kernel with these additional options:
options KDB
option DDB
options INVARIANTS
options INVARIANT_SUPPORT
options WITNESS
options DEBUG_LOCKS
options DEBUG_VFS_LOCKS
options DIAGNOSTIC
Here is the build date:
FreeBSD charon.confluentasp.com 7.0-BETA4 FreeBSD 7.0-BETA4 #6: Tue Dec
11 09:05:50 EST 2007
mikej at charon.confluentasp.com:/usr/obj/usr/src/sys/CHARON i386
(I cvsup'd source on this day just prior to kernel build - tag=RELENG_7)
Now when my SCSI array is plugged into the AHA-2944 controller the
kernel panics on boot. If the array is not plugged
into the controller the system boots and runs fine.
I've read the handbook and tried to follow what posts I read as to what
would be of use in trouble shooting this.
Please don't shoot the messenger. I'll be glad to supply and additional
information - this box is not in production
so I'm willing to try anything.
Just to note, the controller and array had been in production under
6.2-RELEASE and prior versions and has been running
for years without any problems.
Thanks.
