Sam,

This message indicates that the firmware engine wound up in its
interrupt handler with no status indicating an interrupt should
have occurred.  I'm not sure why this is happening in some configurations
(yours is not the first), but it seems to be harmless enough.  I
would love to better understand why this is happening, but without
being able to replicate the problem here (and I have tried), I
don't think I can do much other than just turn off the message in
the driver.
