  wifi crash after awakening from suspend

Status in linux package in Ubuntu:

Bug description:
  After awakening from suspend, the wifi does not work anymore (neither
  does the Ethernet interface).

  It seems the wifi hardware sends an error which cannot be correctly
  interpreted by the OS.

  In attachment, I give an extract of the syslog. Is that a linux
  problem, or specific to my hadware?

  Thanks in advance.
