I've temporarily attached a Seagate ST32151N to a 1542B on a -current
system to try and setup the disk for another system.  Unfortunately,
although the disk reports it is OK, I can't read or write.  The
relevant probe messages are:

Oct 24 15:05:50 /kernel: aha0 at port 0x334-0x337 irq 11 drq 6 on isa0
Oct 24 15:05:50 /kernel: aha0: AHA-1540/1542 64 head BIOS FW Rev. 0.5 (ID=41) SCSI Host Adapter, SCSI ID 7, 16 CCBs
...
Oct 24 15:05:51 /kernel: da0 at aha0 bus 0 target 0 lun 0
Oct 24 15:05:51 /kernel: da0: <SEAGATE ST32151N 9470> Fixed Direct Access SCSI-2 device 
Oct 24 15:05:51 /kernel: da0: 5.000MB/s transfers (5.000MHz, offset 7)
Oct 24 15:05:51 /kernel: da0: 2049MB (4197405 512 byte sectors: 64H 32S/T 2049C)

When I try to read or write the disk (eg `disklabel da0', `dd
if=/dev/rda0 ...' or `dd of=/dev/rda0 ...'), I get:

Oct 24 15:10:39 /kernel: (da0:aha0:0:0:0): CCB 0xc2d78508 - timed out
Oct 24 15:11:21 /kernel: (da0:aha0:0:0:0): CCB 0xc2d78508 - timed out
Oct 24 15:11:21 /kernel: aha0: aha_cmd: Timeout waiting for adapter idle
Oct 24 15:11:21 /kernel: ahainitmboxes: Initialization command failed
Oct 24 15:11:21 /kernel: aha0: No longer in timeout

Does anyone have any ideas?
