Subject: suspend-to-disk issue with an external USB boot device

I can successfully boot from an external USB drive (detected as
/dev/sdb, the internal hard disk is always detected as /dev/sda).
Suspend-to-ram works fine. Suspend-to-disk looks ok during hibernation
phase. However when I wake up the system, then the hibernation isn't
detected. The only message I get is from the Gentoo init scripts:

swapon: /dev/sdb2: software suspend data detected. Rewriting the swap
signature.

I tried both my home-brewed kernel as well as initramfs kernel (created
with genkernel) - no luck.

Now I'm wondering where to start to find the root cause.
