As far as I can tell, the current /sys/power/state code doesn't actually deal with this situation - if S4Bios is detected, the list of available states seems to be set to PM_DISK_FIRMWARE. Echoing platform to /sys/power/disk appears to do nothing. Removing this check lets me use pmdisk. 2) When doing a suspend to disk, the console changes and spends some time sitting around before starting to free memory. At this point, I get some ACPI errors saying "Unable to acquire interpreter mutex". -- Matthew Garrett | mjg59-lk@srcf.ucam.org
