<p>Tried to find out the "default superslotes" for an OpenPower 720. Please try either slot 2 or 5. I delayed my response to make certain that these were indeed the superslots. I am still not a 100% certain -no point waiting beyond a certain stage.<br>
<br>
If you can please go ahead and try these and let us see what happens. Also can you provide the output of "lspci -v" before you load the ib_mthca?<br>
<br>
The firmware I was referring to was the OpenPower firmware, not that of the HCA.<br>

<tt>I've tried a few things, but still seem to get the same error. My<br>
testing has been on 2.6.13.1, with SVN IB code (as of Monday). The<br>
ib_mthca module reports my HCA FW version to be 3.2.0 (which is<br>
admittedly old). Updating this old firmware will likely be my next<br>
step.<br>
<br>
Originally, I had installed the card in slot 1. I've since poked<br>
around in a PDF file I found on IBM's site and concluded that I should<br>
have installed the card in slot 3, though I'm still not overly<br>
confident about that. I/O Adapter Large Capacity is also now enabled<br>
(it wasn't previously, and changing it while the card was in slot 1<br>
didn't seem to affect anything).<br>
<br>
Is somebody aware of a clear way to identify which of the slots in the<br>
720 are "superslots," as I've had no luck so far in my hunt in the<br>
documentation. Most likely, I've mistakenly skipped over it.<br>
<br>
Thanks.<br>
