Ok so one more update. I discovered ALL my problems with hibernate/resume, code 58 holds on startup and portable drives going zombie was due to the lousy USB3.0 chip and Renesas drivers on this motherboard. What's worse is that Intel KNOWS they stink (see multiple posts a year ago when first reported) and have done NOTHING about it. Now they will not even reply to messages about it on this board.
The solution, for $31 at Amazon is an Inateck pcie USB3.0 card. 5 rear ports and a plug for the front ones. My machine boots faster, hibernates and resumes without any special consideration and my portable drives stay connected all the time. Must turn off USB3.0 in Bios.
P.s. I tried everything, new drivers, bios the works. Took week of my own time to diagnose but problem is solved. Thanks intel for nothing. No wonder you are getting out of the desktop board business.
