Attached is a full diff between dmesg from -rc3 and -rc6 with your debug 
patch.

I've cleaned up the diff a bit to make it more readable (mostly removal of 
changes that I always get due to random USB load order changes - UHCI 
still frequently loads before EHCI).

The most interesting points are probably at lines 298-346 and 639-649.

At the bottom there's a fairly long addition from the few suspend/resume 
cycles I did (again, running with the debug patch).
