The system booted fine after the update, but now I'm back to emergency mode, and I have no idea what I did :-( This is now starting to get very frustrating. After booting of an old kernel I ran yum -y update and updated to the latest kernel and selinux packages plus other stuff. I rebooted and the system lo and behold booted up to the graphical login, there was no emergency mode login prompt :-) This was running fine for a while. I plugged in my external USB 3.0 hub, which worked fine with 3.13.5 prior to me screwing things up :-) and nothing happened, it did not see any drives. I unplugged the drives and then plugged them in one by one and it saw one but not the other 3. So I unplugged the hub after making sure no drives were mounted and rebooted. Guess what? I'm now back to the emergency mode prompt. If I boot off an older kernel I again get the emergency mode prompt. What was working fine earlier no longer works. Here's the shutdown log https://www.amazon.com/clouddrive/share?s=-h_XGxyZT-ws_rNy16Jr0g This system has been running Linux since December and I've never had as much trouble with it as I have had these last few days.
