Michael,
Sorry for the long delay in replying, I was on vacation for 10 days, then
when I returned, the OFED RC5 release was imminent, so I decided to wait
to install it before persuing this further. Of course, when I did, the
problem mysteriously went away. The ib_mthca module now initializes
correctly on both EM64T machines. I noticed some discussion between you
and Roland about making the parameter "fw_cmd_doorbell=0" the default. Did
this occur in RC5?

In case the problem comes back again with RC6, below is some information
on the machine that had the problem.
