I'm not sure what's going on.  mthca_init_one() is bailing out and
disabling the device on the way out, and iosapic_unregister_intr() is
warning (not actually an oops, just WARN_ON(1)) because it can't find
a valid IRQ number.

Does this happen even without MSI turned on?

Can you build your drivers with CONFIG_INFINIBAND_MTHCA_DEBUG=y and
then do "dmesg -c > /dev/null && modprobe ib_mthca" and send the
output of "dmesg"?  Don't worry about sending the whole thing to the
list, it can't be that giant.

Thanks,
  Roland
