I experienced a similar problem on a system with a 3ware RAID
controller, driven by twe(4). I noticed that the problem only occurred
when the twe card was in the first PCI slot; if it was out, or if it
was in another slot, everything worked fine. I haven't had a chance to
dig much deeper than that, but that and the location of the crash
makes me suspect a problem around the apic programming and dispatch.
