$ cat /proc/scsi/scsi 
Attached devices: 
Host: scsi0 Channel: 00 Id: 00 Lun: 00
  Vendor: SEAGATE  Model: ST318451LW       Rev: 0003

This disk i(/dev/sda) is an Ultra 160 (SPI) connected to 
a Tekram DC-309U3W controller.

The reported problem occurs with all disks seen by the scsi
subsystem in lk 2.5.21 that I have tested including usb mass
storage and ieee1394 sbp2. I am not aware of any ATA disks
that support ATAPI and hence could be used with ide-scsi
driver (if it didn't crash in 2.5.21).

My guess is that there is a problem in the block (or genhd)
subsystem.
