Hi Jim,

Yesterday, my BeagleBone Black (Rev C) was working fine. Today,
when I powered up the system eth0 is not coming up.
$ ip addr show eth0

group default qlen 1000
link/ether c8:df:84:d7:07:a6 brd ff:ff:ff:ff:ff:ff
How do I get eth0 to come up again? I've tried rebooting the
board with `$ sudo reboot` and restarting the service with `$ sudo
/etc/init.d/networking restart` but neither helped. Yesterday, I
installed smbclient and cifs-utils, and deleted the /usr/src and
/usr/include directories. Does anyone know how to get eth0 working?
There is a known problem with the Ethernet MAC not coming up on boot.
This is likely to happen when you're powering the BeagleBone through
the barrel connector. If this is the case, a simple reboot won't help.
You need to shut down, remove power for 10 seconds and reconnect
power. IIRC the physical reset button also helps.
physical reset button is a soft reset. a power cycle is the only way.
