Title:
  [enhancement] e1000e should handle defective hardware more gracefully
  (causes intermittent freezes)

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  When e1000e is loaded and the interface is up the systems freezes for
  about a ½ second every 4 seconds. I took special note of these lines
  in the dmesg output:

  [    2.339056] e1000e 0000:00:19.0 (unregistered net_device): Failed to initialize MSI interrupts.  Falling back to legacy interrupts.
  [    2.900771] e1000e 0000:00:19.0 (unregistered net_device): Hardware Error

  And one additional Hardware Error everytime I brought the interface up
  or down.
