Sigh, I knew I'd forget something.   :)

We are running 4.2-STABLE as of about a week ago.

As soon as we had the problem we upgraded the firmware. Here is the
revelant parts of dmesg:

twe0: <3ware Storage Controller> port 0xef60-0xef6f irq 10 at device 20.0 on pci0
twe0: 4 ports, Firmware FE6X 1.01.18.001, BIOS BEXX 1.06.00.001
twed0: <RAID10, Normal> on twe0
twed0: 146615MB (300268800 sectors)

Will do. Rebuilding the kernel now.

Thanks for the *really* quick response.  :)
