The Advansys driver /proc output indicates 4 SCSI bus resets were received. So the
SCSI bus is probably hanging, commands are
timing out, and the mid-layer is sending the Advansys driver reset commands. Even
though it works under Windows check the most
common SCSI problems first - cabling and termination.
If you're using only one connector on the adapter (and one cable) only the last drive
should be terminated. The adapter will
terminate its end. Also can you use the CD writer without the hangs if you remove the
Plextor drive?
Can you explain more what you mean by the scsi chain is out of order after mounting
the device? Also I don't know why your listing
says you have a 2.2.13 kernel but you have the Advansys 3.1E driver. The official
2.2.13 kernel has the Advansys 3.2F driver. If
you don't know why yours is different maybe you should get the original kernel source
and build a new kernel from scratch to see if
the behavior changes.
