On my laptop (AVERATEC 3150H) I have seen it stuck in the infinite loop
in acpi_sleep_machdep (acpi_wakeup.c). Apparently my BIOS handles
suspend as soon as proper bits are set in the register and resumes from
there as well instead of calling resume vector code. Commenting this
loop out and restoring interrupts after it got me to suspend with the
same power savings as Windows (which is not much -- about 3x normal use
battery life). I don't know how widespread this behavior is, so YMMV.
