Thanks, will take a look.  It does seem this is on an error path:

 > [  606.818317] ib_mthca 0000:c4:00.0: NOP command failed to generate

 > [  606.826709] ib_mthca 0000:c4:00.0: BIOS or ACPI interrupt routing problem?

So your system already had problems -- the driver didn't get an
expected interrupt from the device.
