Hi,

today I replaced my good old NCR 53c810 by an Adaptec 2940UW. After
adapting the mapping everything works fine except my Sony SDT 2000
DAT tape. If I try to write to it with "tar" I get error messages
like this:

st2(ahc0:4:0): timed out in dataout phase, SCSISIGI == 0x0
st2(ahc0:4:0): BUS DEVICE RESET message queued.
Bus Device Reset Message Sent
st2(ahc0:4:0): timed out in message out phase, SCSISIGI == 0xa4
ahc0: Issued Channel A Bus Reset #1. 1 SCBs aborted

Here's what the kernel says during system startup about the DAT:

ahc0:A:4: refuses WIDE negotiation.  Using 8bit transfers
ahc0: target 4 synchronous at 5.0MHz, offset = 0x7
st2 at scsibus1 targ 4 lun 0: <SONY, SDT-2000, 2.05> SCSI2 1/sequential removable
st2: drive empty

A Tandberg TDC 3660 and an Exabyte 8200S both work with the Adaptec,
the Sony SDT 2000 works with the NCR.

I would like to know if anybody else uses such a tape drive under NetBSD
in conjuction with an 2940(UW) because I'm not sure if this a bug in
the driver or some kind of hardware problem.
