Not sure. Its the first time I have ever seen this error.  In the past,
the box would be crashing for other reasons after 2-5 days.  However,
with the fixes from glebius and mlaier all seemed to have been fixed.
The box was up 11 days when it hung with that error. I could not even
break into the debugger. Hence, I was thinking perhaps the hardware is
all of a sudden showing an issue.
The two active NICs are using the legacy interrupts
