Areca ARC1160 PCI-X 133MHz (83.333MHz, offset 32, 16bit)

[Jonas Maanmies]

Hello list.

I have a Areca ARC1160 PCI-X 133MHz card in a PCI-X 133MHz slot on my 
mainboard, running FreeBSD 6.2-RELEASE i386

The oddity is how the system detects the card.

pass2 at arcmsr0 bus 0 target 16 lun 0
pass2: <Areca RAID controller R001> Fixed Processor SCSI-0 device
da0 at arcmsr0 bus 0 target 0 lun 0
da0: <Areca System R001> Fixed Direct Access SCSI-3 device
da0: 166.666MB/s transfers (83.333MHz, offset 32, 16bit), Tagged 
Queueing Enabled
da0: 152587MB (312499712 512 byte sectors: 255H 63S/T 19452C)


I can clearly remember getting >166MB/s to the same disks in the same 
machine, on the same controller previously. I think it was 6.1 I ran 
before updateing to 6.2-RELEASE

I'll test booting on a 6.1 CD later on, to see if that finds the card 
properly, but it's a bit of a logistics problem with FreeBSD / USB-CD 
problems so I thought I'd send it first.

(maybe) relevant stuff from dmesg:
