Make sure your kernel has this patch: http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=cef1d00cd56f600121ad121875655ad410a001b8 Alex > > Did some tests: > > radeon module loaded (usual state): > After "echo mem>/sys/power/state", the laptop suspends correctly (power > LED > blinks). When power button is pressed, power LED goes on and that's all. > No more activity, machine is frozen completely. > > radeon module not loaded at all: > Laptop resumes correctly (keyboard LED work, network works), only the LCD > is > blank (obviously).
