Perhaps the drive
will function correctly if tagged queing is disabled for it.  You
can do this only for target 1 with the "tag_info" option.  There may
also be firmware updates for this drive.

Okay I used tag_info as you directed and set the Quantum Fireball drive
to
use a maximum tag depth of 8 (like the old driver used) and everything
seems to work fine.

So can you point me to where in your driver code the depth of the tagged
queueing is dynamically determined?  I would like to play around a bit
with the driver code to see if I can tell if the Quantum Fireball is
simply spitting back bogus info or and if so what?

IIRC, early Fireball models reported support for TCQ and didn't even
support it.  This from discussions on the NetBSD forums a few years
back.  I wouldn't be surprised if the drive were reporting wrong
info....  From what I gather, Quantum's high end drives were pretty
decent, but I have a stack of dead Fireballs to prove that their low end
drives weren't....  :-|
