There are two different, or should I say separate, firmware. One is
permanent, either in EPROM or flash, and one is volatile. The permanent
one is what you upgraded from FTP. I'd guess that what happened here is
that the version of the volatile firmware loaded by the Xen kernel isn't
compatible with this permanent firmware rev, for one reason or another,
or the wrong volatile firmware was loaded due to device
mis-identification, i.e. volatile firmware for one of the other
Broadcomm NICs was loaded. Some of the output you posted seemed to
suggest this may have been the case. I have seen such a problem before
but it is pretty rare.
