Hi,

on NetBSD/i386 1.4.1, I see

ahc0 at pci0 dev 11 function 0
ahc0: interrupting at irq 11

sd2: 8748MB, 11474 cyl, 5 head, 312 sec, 512 bytes/sect x 17916240 sectors

where sd2 is a brand new 9G disk. Why is it attached with only 10 MHz
transfer rate? (The AHA 2940UW has its "ultra" option activated).

The three disks hang off the wide channel, and there are a CDROM and a 
Tandberg SLR5 on the narrow channel.

Any ideas?
