OOhhhh, you have something bad going on here.  And it's probably not related
to the Ethernet device itself.  Both the IDE and the rtl8139 drivers are
complaining that their interrupt lines are blocked.

What interrupt line is the IDE controller on?
  (It's likely IRQ14.  If not, that might be a place to look for a problem.)

Check /proc/interrupts while this occurring, if you can -- I'm guessing that
some interrupts counts will not be incrementing.

Do you have any unusual devices that might be blocking interrupts?
