I'm having communication problems between an sym53c895 host adapter and
an old/slow SCSI-1 device. I'm using FC4 linux with the most recent FC4
-released kernel 2.6.12-1.1398. The sym53c8xx_2 driver version is
sym-2.2.0. The sym53c8xx_2 driver was working for me until the 2.6.10
kernel release (driver version sym-2.1.18m). After that point, the
driver has trouble probing the device. The initial inquiry command
appears to complete most of the time, but read capacity does not. I put
some print statements in scsi_glue.c to look at the CDB contents before
scsi commands are issued and the buffer contents after commands
complete, and some data does get received. The read capacity command,
for example, should get 00 01 FF FF 00 00 02 00, but instead gets 00 00
00 00 00 01 FF FF.
I append a portion of the driver output from /var/log/messages with
driver parameters verb=2 debug=0x246. If the full output or other
debug= options would be helpful, I can send the full file.
The SCSI device in question is strictly async, rejects all messages,
does not disconnect and its transfer speed is less than 5MB/s. It is
currently the only device on the bus. It works fine with the aic7xxx
driver on a different desktop machine running the 2.6.12-1.1398 FC4
kernel release.
Does this ring any bells with anybody?
I will be out of my office until 8/16, but I will try to check in
periodically until then.
Thanks for your help,
Ted Hildum
