Strange, I'm not sure what's going on.  Some firmware commands are
succeeding and then one fails with a status that the firmware should
never return.

Taking a wild guess about what might be affecting this, how much memory
does your system have installed?

Can you make sure your kernel is built with CONFIG_INFINIBAND_MTHCA_DEBUG=y
and then send the output of loading the driver with the debug_level
module option set to 1?

Thanks,
