I seem to be running into a problem getting a Mellanox Infinihost
Infiniband adapter working on my IBM p550 (a 9113-550). I'm using
Debian squeeze, and tried upgrading to the 2.6.35.7 kernel without any
help.
I get the following messages in dmesg:
[ 4.972548] ib_mthca: Mellanox InfiniBand HCA driver v1.0 (April 4,
2008)
[ 4.972564] ib_mthca: Initializing 0000:c1:00.0
[ 4.972674] ib_mthca 0000:c1:00.0: Missing DCS, aborting.
The problem looks the same as a problem I ran into with OpenFirmware on
a Sun V880, which was fixed with this patch by Dave Miller:

I spent some time looking at the equivalent function on powerpc, but
didn't a block of code that looked similar.
Any suggestions?
I have dmesg, the dev .properties from openfirmware, and lspci -v from
the machine:
