Title:
  Linux crashes 1~5 mins after successful suspend/resume if no LAN
  activity

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  12.04 64 bit
  linux 3.2.0.17.17

  First noticed this odd bug last weekend, after testing the new updated
  linux 3.2 with rc6 handling and have now had the time to get more
  details. The crash is repeatable, on the latest updates, as at
  20120304-14:00 UTC:

  Clean boot
  Start (say) xsensors or anything for status monitoring that does not use LAN
  Start mtr x.x.x.x in a tem window (anything with frequent LAN keepalives)
  Suspend
  Resume
  System comes back, apperently successfully, with normal operation including live LAN
  Stop LAN activity (stop mtr, above)
  System crashes in 1~5 minutes

  The crash is a static-screen freeze, no keyboard or mouse input
  working and no layer3/4 on the LAN (remote ssh not possible, no IP).
  The variance in the 1~5 minutes until the crash is possibly due to
  other keepalives, such as the weather applet or ntp.

  I never normally use suspend on the desktop, so am not aware if this
  bug existed before last weekend / Feb 26. I have been testing 12.04 as
  my main home pc for 2 weeks now and linux has been stable in every
  other usage for me.
