Ok, so you first push as much as you can to swap to free half
of memory. Then, when you say you copy used memory, I assume you copy
all of RAM including kernel memory (kernel data structures etc...)
right ?
What do you mean by "stop everything" ? Stop user processes ? Kernel
threads ? both ? Then, you only save device state (and then suspend
devices) after you have "stopped everything" ?
Ben.
