The issues that remained with Centos7 and Scientific7 with the existing 6.0.x kernels were not expected to be fixed until 6.2 according to the developers, however, 6.0.12 appears to have fixed them as both machines booted cleanly after the upgrade last night.
Also, I adjusted the clock on ice from 4.3 Ghz to 4.2 Ghz as it was ever so slightly unstable at 4.3 Ghz.
Lastly, Manjaro is restored, but your existing ssh keys will not work as this is a fresh install so you will need to delete and create / propagate new keys. There is much software not yet installed, so if something you need is missing please send a note to support@eskimo.com and I will prioritize.
