Yes, I've noticed this too (on an ASUS SP3G with NCR 53c810 chipset,
talking to a Sony CDU-76S). I had a minor attempt at fiddling with the
timeout values in /sys/scsi/something.c but it didn't change.

Apparantly people with AHA1542 type SCSI controllers don't have any
problems, so maybe some timeout stuff in the NCR driver needs tweaking?
