On board LAN disabled after soft reboot
*edit:
okay, updating drivers didn't fix it.
applying the latest kernal security patch seems to be the cause of my problems. 2.6.39-400.109.5.el6uek.x86_64
everything up to that patch and the on board LAN worked great on "shutdown -r" and "shutdown -h"
After applying the kernal patch, the on board LAN is getting it's MAC wiped out to 00:00:00:00:00:00
I have a workaround. I can either NOT apply that security patch... or I can do the following:
I disable the NetworkManager daemon, shutting down its service. I enabled the simple "network" service instead so that I can manually set it up.
chkconfig NetworkManager off
service NetworkManager stop
chkconfig network on
then I manually apply the missing hw# (MAC address) to eth0 (eth0 being the on board LAN).
ifconfig eth0 hw ether bc:f5:f4:9e:47:93
then I activate it
ifup eth0
And that fixes it until the next shutdown and restart the system again. Then I have to reassign the MAC and activate it again.
To avoid all of that I have a simple script that I run at startup: /etc/init.d/eth0mac
all it does is this:
ifconfig eth0 hw ether bc:f5:f4:9e:47:93
ifup eth0
It is a workaround but it does the trick. Now, if I remotely issue a shutdown/restart.... "shutdown -r now" it will come back online on startup and I can log in again.
