[openib-general] EEH: MMIO Failure on Power5

[Thaddeus Ternes]

I've tried a few things, but still seem to get the same error.  My
testing has been on 2.6.13.1, with SVN IB code (as of Monday).  The
ib_mthca module reports my HCA FW version to be 3.2.0 (which is
admittedly old).  Updating this old firmware will likely be my next
step.

Originally, I had installed the card in slot 1.  I've since poked
around in a PDF file I found on IBM's site and concluded that I should
have installed the card in slot 3, though I'm still not overly
confident about that.  I/O Adapter Large Capacity is also now enabled
(it wasn't previously, and changing it while the card was in slot 1
didn't seem to affect anything).

Is somebody aware of a clear way to identify which of the slots in the
720 are "superslots," as I've had no luck so far in my hunt in the
documentation.  Most likely, I've mistakenly skipped over it.

Thanks.

Thaddeus
