Title:
  [radeon] suspend fails in 14.04 with Juniper and Caicos on an Asus P6T
  SE

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  Suspend to RAM fails for me with the radeon driver and two cards on an
  Asus P6T SE motherboard: Juniper and Caicos. Even at console in single
  user mode (to eliminate Xorg) and with "echo devices >
  /sys/power/pm_test" and "echo freeze > /sys/power/state" to narrow it
  down to unloading modules (it works with "freezer" sent to pm_test).

  Unloading the radeon module (needed to blacklist with a kernel
  parameter first) lets everything work.

  Tried the stock Ubuntu Trusty 3.13.0 kernel and also tried using
  3.14.10 and 3.15.3 from the PPA. All fail, but 3.15 has the screen go
  white after a bit so that's new.

  Tried installing various new X stuff that probably is totally
  unrelated via ppa:oaibaf/graphics-drivers

  Tried disabling dpm with the radeon.dpm=0 parameter.

  Tried disabling synchronous suspend with "echo 0 > /sys/power/async".

  Not sure what else to try?
