93 saves the state of the machine to a filesystem or to a partition and switches
94 to standby mode. Later resuming the machine the saved state is loaded back to
101 swsusp saves the state of the machine into active swaps and then reboots or
104 state. If the option `noresume` is specified as a boot parameter, it skips
109 of the hardware, write to the filesystems, etc.

152 inconsistent kernel state which would certainly result in an oops.

219 it's useless for suspend-to-disk. (And I do not see how you could use
220 it for suspend-to-ram, I hope you do not want that).
240 Which means that you still need that FREEZE state, and you get more

457 modes like "suspend-to-RAM" or "standby". (Don't write "disk" to the
458 /sys/power/state file; write "standby" or "mem".) We've not seen any
459 hardware that can use these modes through software suspend, although in
469 There is a work-around for this problem. For more information, see

502 slow, take a look at suspend.sf.net -- userland suspend is faster and
