Adaptec 29160N + Sony AIT SDX-400C

[jarausch at igpm.rwth-aachen.de]

Hi

I am in need of your help.

On my new server (Serverworks motherboard)
I have an Adaptec 29160N Ultra 160 SCSI controller
and a Sony AIT-1 tape driver attached to it.

My system is Linux (kernel 2.4.18-rc2 with
linux-aic7xxx-6.2.5-2.4.17.patch)

The Sony tape drive is detected and I can do
mt status without problems.


now 

dd if=something of=/dev/st0
gives

st0: Error with sense data: Info fld=0x0, Current st09:00: sense key
Aborted Command

then dd says it's writing 2 (of 3) blocks
and notifies me about an I/O error.

trying a 'tar' onto that tape
the system hangs,
the 'busy' LED on the tape driver is blinking.

I can only 'recover' if I turn power off at the tape
drive.
I get
Unexpected bus free in Data-out phase
SEQADDR == 0x1ad

which is probably due to the power off

but then I get

st0: Error 70000 (sugg. bt 0x0, driver bt 0x0, host bt 0x7)
st0: Error 10000 (sugg. bt 0x0, driver bt 0x0, host bt 0x1)
st0: Error on write filemark
st0: Error 10000 (sugg. bt 0x0, driver bt 0x0, host bt 0x1)

Is that 
- a hardware failure with this (brand new) Sony AIC drive.
- a problem with the Adaptec 29160N SCSI controller card
- a problem with aic7xxx driver
- a Linux kernel problem

I very much appreciate your help.
