When you power-cycle the HV crates, they go through a startup sequence that takes a non-neglible time (15 seconds? 30?). I think if you try to ./BOOT during that time, the IOC won't be able to talk to the crate(s), and you'll still have trouble. So if you use the remote power-cycle, wait a bit (but less than a minute, I'm sure) before the ./BOOT.

Other than that no problems, took runs 6022-6032 with 6014-6021 JUNK (when I had the coda problem) and 6030 JUNK - the dreaded "9th run" problem again.
