[Bug 137666] Re: [gutsy] rt2x00 and NetworkManager causes hang when suspending

[Steve Langasek]

If this is still an issue for anyone with later releases of Ubuntu
(10.04 or later), please open a new bug report against the linux
package.  The behavior described here indicates a driver bug; we should
work around this in the suspend-resume handling scripts only as a last
resort.

Title:
  [gutsy] rt2x00 and NetworkManager causes hang when suspending

Status in “acpi-support” package in Ubuntu:
  Invalid
Status in “network-manager” package in Ubuntu:
  Invalid

Bug description:
  Binary package hint: network-manager

  I'm using a wireless card with the rt61pci (rt2x00) drivers and when
  NetworkManager tries to take down the interface when suspending the
  machine, it sometimes will give the error "unregister_netdevice:
  waiting for wlan0 to become free. Usage count  = XX" over and over
  again, esentially locking up the machine until I do a hard reboot.  It
  does not happen all the time, and never when shutting down so far.  It
  also does not happen if I remove network manager and set up the card
  using the interfaces file, so it seems to be something with how it
  disables the interface.  Using Ubuntu Gutsy tribe 5.
