spin lock smp rendezvous panics

[Doug White]

I've been getting this panic during buildworlds for the past few days from
-CURRENT:

spin lock smp rendezvous held by 0xffffff005ae39be0 for > 5 seconds
panic: spin lock held too long
cpuid = 0
KDB: enter: panic
<hang>

debug.kdb.stop_cpus=0 is needed to get into ddb.

This is a HDAMA with 2 Opteron 244s with 2GB RAM and a 3ware twe
controller.
Anyone else having problems with this?
