Description of problem:

Last night I have installed Fedora 20 on a SD card on a new Beaglebone Black.

It booted and rebooted successfully with the default kernel.

I have proceeded to do a 'yum update' and this morning I have rebooted it with kernel 3.12.6-300.fc20.armv7hl then it keeps oopsing.

I got the following two oopsen:

[  OK  ] Started NTP client/server.
