Yes; I'm not sure what that is, but I get it too (for successful
hibernations).

I suspect the problem is that something about the USB storage subsystem
doesn't persist across a power-cycle in the stock kernel. You need a
kernel compiled with a USB persistence option (I think it's
"USB_PERSIST", but I might be wrong) in order for mounted filesystems
or a swap partition on a USB or SD storage device to persist across a
reboot. Sorry I don't have more detail about where to get a Debian
kernel with USB-persist on; I use Ubuntu-eee which has that on in the
kernel by default. (Take this with a grain of salt; this is just
something I've picked up from various tutorials about how to make this
work in Ubuntu.)
