<br><font size=2 face="sans-serif">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 "</font><font size=2><tt>fw_cmd_doorbell=0</tt></font><font size=2 face="sans-serif">"
the default. Did this occur in RC5?</font>

</tt></font>
<br><font size=2><tt>In case the problem comes back again with RC6, below
is some information on the machine that had the problem.</tt></font>
