'0' is off.  255 will just get rounded down to 253, the maximum allowed
number of tags.

Try '0'.

Known bad firmware.  Try upgrading to 0F0J if you can find it somewhere.
Quantum used to have it on their ftp site, but sadly this seems to be
gone now that Maxtor has acquired their disk drive division.

I can't recall if it was the 1060 or the 1080 that had so many problems
with tagged queuing, but it was one of the two.

Just this snippet doesn't tell much of anything.  You need to run with
aic7xxx=verbose and record *all* of the messages displayed by the
driver.  You may need to use a serial console to do this.
