I had a somewhat equivalent problem with suspend-to-ram (working but no wakeup) which required two patches: - add PWRB and LID0 as wakeup devices[1] - ignore PRWF since it doesn't send acpi events [2] It was with a 2.6.8-rc2 kernel, so the situation may have changed since then. OG. [1] Seems added now, did you check the contents of /proc/acpi/wakeup_devices ? [2] http://bugzilla.kernel.org/show_bug.cgi?id=1920
