I am trying to use an Apdaptec 1520B SCSI controller
with a Sony DAT tape drive, following is the machine configuration:

The 1520B controller appears to be a new Adaptec product, it has
Adaptec AHA 1510/20/22B printed on the PCB, and is a plug & play device.
Plug & play was disabled in the adapter BIOS.
The initial FreeBSD installation was made from a SCSI CD-ROM using
the Adaptec 1520B controller, and there were no problems.
Tape rewind, eject commands etc work fine with the controller,
however when using tar to copy files to the tape I am getting a
2 minute operating system freeze where num lock and caps lock will not
work, I sometimes even had the hard drive light stay on for the
duration of the 2 minute freeze. After 2 minutes I reveived the
following error messages, and then the system returned to normal:
st0(aic0:2:0): ABORTED COMMAND info:2800 asc:4b,0 Data phase error
tar IO error message
st0(aic0:2:0): HARDWARE FAILURE info:1 asc:44,0 Internal target failure
I tried the same card in a 486/66 with 2.2.2-RELEASE and encountered
a similar freeze except that the numlock would work however no key
input was accepted, ie ALT F2 to swap virtual console did not work.
I tried the same card in the 486/66 with 2.1.7-RELEASE and encountered
a freeze except that I could swap virtual screens, however no key
input was accepted.
In all instances the error messages were the same, and the computer
returned to normal after the messages.
Is this Adaptec 1520B supported by FreeBSD or do I have a fault with
the controller? I replaced the 1520B with a 1542 controller and all
is working fine.
Thanking you in advance.
