Firewire drives

[Michael Ault]

I have attempted to use ACOM and Western Digital
firewire drives on my new cluster. They need to be
able to accept multiple logins. The Old 80 gig western
digital works fine. The new 120 gig doesn't. The
oxford911 chipset is used in the wd drive.
 
The oxford911 I thought was supposed to work with a
shared connection. I can connect with one system, but
the other reports that the drive is telling it that it
has 37 million connections (or whatever the max value
is for big integer) and refuses a second connection.
Has the microcode been altered since the 80 gig drive?
Is there any way to patch this so it will accept
multiple connections?
Here is the dmesg output from the server that connects
ok:

Now here is the one that doesn't:

It worked fine with the old 80 gig firewire only
drive, but this combo is giving me fits.

Looks like the microcode has been altered.
