(probe23:arcmsr0:0:16:0): inquiry data fails comparison at DV1 step

[Andre Oppermann]

Today I upgraded an AMD64 server from FreeBSD 6.4 to 7-STABLE and got a big
nasty surprise with the Areca RAID controller:

arcmsr0: <Areca SATA Host Adapter RAID Controller (RAID6 capable)
 > mem 0xfdbff000-0xfdb400000 irq16 at device 14.0 on pci18
ARECA RAID ADAPTER0: Driver Version 1.20.00.15 2007-10-07
ARECA RAID ADAPTER0: FIRMWARE VERSION V1.46 2009-01-06
arcmsr0: [ITHREAD]
...
(probe23:arcmsr0:0:16:0): inquiry data fails comparison at DV1 step
run_interrupt_driven_hooks: still waiting after 60 seconds for xpt_config

 From here on it hangs and repeats the last message with some sort of
exponential backoff. Ctrl-Alt-Del to reboot doesn't work but ScrollLock
does. Hard reset is required to reboot.

Booting the old 6.4 kernel works and the system comes up again with full
access to the RAID array.

Any help appreciated.
