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: http://ns3.spinics.net/lists/linux-rdma/msg01779.html 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: http://ned.rcac.purdue.edu/p550-ib/dmesg http://ned.rcac.purdue.edu/p550-ib/ib-of-device http://ned.rcac.purdue.edu/p550-ib/lspci-v Pat -- Purdue University ITaP/Research Systems -- http://www.rcac.purdue.edu
