I does not help, apparently. Below is what I've just got on -rc4 with this
patch applied. Please note that there were two attempts to suspend the box
in a row and I've stopped some memory-consuming apps after the first one.
Now, as I've stopped all of the apps that I wanted/could stop before suspend,
the box is unsuspendable for practical purposes.
The USB-related stuff in between is retained for completeness.
