Further testing - my netbook now resumes if it hasn't entered a "second level" of suspension. In the "light" suspend mode, the laptop wakes up when I press a key. In the "deep sleep" suspend mode, the laptop doesn't wake up on a key press, only when I press the power button. In the second situation, the wifi led turns on, the hdd led flashes, and the video stays off. This happens both with the open source driver and the binary fglrx driver (with acpi_sleep=
When the laptop has entered this "deep sleep" mode, sometimes even a poweroff isn't enough. I need to take out the battery and put it back, or it won't power on, giving the same symptoms - wifi led on, hdd led flashes once. Again, this happens with both open source and binary amd/ati drivers.
In windows suspend/resume works, and after long period suspended the laptop hibernates. Maybe there is some trigger to make it hibernate (which I can't find in the BIOS) that is hanging when it is trying to call some function we don't have under linux?
