I know what is happening now.  Can you try the attached patch?  I'm 
disabling the requeue and discarding the message when an IPMB message is

not deliver any messages because something is already in the queue.

No, it's an artifact of a lousy hardware interface.  Very few IPMI 
interfaces support interrupts, so they have to be polled :(.
