I have only tested hibernate - some major problems when starting this morning, buts that's probably tuning for in-kernel as against a system setup for ToI.

I also am getting /usr errors again (both on boot and resume from hibernate, can't find some binaries on /usr, but mounts ok later in the sequence -maybe timing) - lack of detailed debug when in the initramfs is a problem - will have to start scattering print statements through it ...

This is on a home gateway/server that's shutdown/powered off overnight. Startup has to be fast as when power comes on (via remote controlled relays) there are PXE diskless NFS systems (mythtv front ends) that time out if it goes through a full boot sequence.
