The man page takes a too pessimistic view of ehci. It works for most
people.

Ok, I have compiled a kernel with ehci in. Here is a snippet of dmesg
output (right after rebooting the box):
da0 at umass-sim0 bus 0 target 0 lun 0
da0: <Maxtor 6 L250R0 BAJ4> Fixed Direct Access SCSI-0 device
da0: 40.000MB/s transfers
da0: 238475MB (488397168 512 byte sectors: 255H 63S/T 30401C)
umass0: BBB reset failed, TIMEOUT
umass0: BBB reset failed, TIMEOUT
umass0: Invalid CSW: sig 0x4628f8ff should be 0x53425355
(da0:umass-sim0:0:0:0): Synchronize cache failed, status == 0x4, scsi
status == 0x0
Note that it displays high transfer rate this time. I've ran 'diskinfo
-t' to check the actual rate; the seek tests have passed but transfers
hung. 'dd' froze either:

^C
Nothing relevant in /var/log/messages. How can I debug it further?
