Hi All
I am facing a strange issue in a host processor (i7) with oracle 6.5 installed in it.
uname -a
Linux SC-2 2.6.39-400.211.1.el6uek.i686 #1 SMP Fri Nov 15 13:38:12 PST 2013 i686 i686 i386 GNU/Linux
Everything was working fine till i rebooted the system and stage to see no interface exist to other than loopback interface. After that i booted the system multiple times but all in vain. Then I reinstall the complete linux as done in a fresh system then it start working again.
lspci output of both working and non working setup is same.

But in the non working machine, no print (regarding igb and e1000e modules) comes after "WARNING! power/level is deprecated" i.e. dca service started print does not comes.
Finally after checking i come to know that 40 modules were not loaded in error case as compared to success one.
After surfing I came to know that this issue was there till redhat 6.3 and redhat 6.4 but was fixed in 6.5 .

Then I manually load hwmon.ko dca.ko and the igb.ko in sequence and then system interface working as expected. But on reboot gone again.
What may be the possible culprit to see in Oracle Linux 6.5
