Bug description:
  Description:	Ubuntu 13.04
  Release:	13.04

  After upgrading to 13.04 suspend and hibernate do not work.
  In terminal window following error is displayed: "PM: Some devices failed to suspend". Then the suspend fails and the screensaver gets activated, requiring a password to unlock.

  SRU INFORMATION
  ---------------
  * Impact: suspend regression in 13.04 with Qualcomm Atheros Gigabit ethernet devices
  * Test case: Suspend is broken in current raring when the alx module is loaded, should work again with the fix; needs to be tested on actual hardware, see comment 56 for positive testing result that this pm-utils workaround works.
  * Regression potential: If the script is malformed, it could potentially break suspend on other devices; this should generate an error in /var/log/pm-suspend.log. Please test suspend on devices without the alx module as well (for the record, Martin Pitt did that on his ThinkPad X201)
