What does the "reboot" swsusp mean?
I am having this (or a similar problem):
echo shutdown > /sys/power/disk; echo disk > /sys/power/state
suspends normally. But after a resume, the moon keeps blinking _and_ I don't get ACPI events anymore. At least all ibm-acpi features refuse to work (hotkeys, lcd-brightness, lid, ...).
I saved some /proc files (interrupts, acpi/processor/power, ...) and compared them before the suspend and after the resume but I could not find any differences.

What is platform_prepare() actually good for when _resuming_? I tried to follow the function calls and it seems to disable a lot of thing instead of re-enabling them...?
