Re: mthca and LinuxBIOS

Hmm, that output all looks fine.  Can you run with the patch below to
see exactly where the QP table initialization fails?  (I haven't
actually compiled this patch so you may have to fix a typo or two)

I'm guessing that the CONF_SPECIAL_QP command is failing, but let's
make sure.

Thanks,
