Post eth0 is missing after reboot


Hello Fellow Linuxers,

This is my first plea for help and I hope I am doing it right.

I am running 64-bit Linux Mint 17.2 Rafaela on an HP EliteBook 8570w (A7C38AV) with 16GiB System Memory and have 'lost' eth0. As I have searched the forums and google and found similar problems, but unfortunately, none of the solutions for those problems resolved mine, I am hoping to find an answer to my problem amongst you.

eth0 appeared to work fine yesterday before I shut down the system, but after starting and logging on today, I haven't been able to get it back online. I am fortunately able to use the wireless connection to access the internet and these forums. The very first thing I tried was 'apt-get update && apt-get dist-upgrade -y' followed by init 6, but that did not help.

I will greatly appreciate any help/advice.

The following is a description of my system and the steps I have taken until now:

Afterwhich, the following was reported by dmesg:

[ 2283.954204] e1000e: probe of 0000:00:19.0 failed with error -2

I also installed kernel 4.2.0-30-generic, booted, repeated modprobe -r e1000e; modprobe e1000e, but the results were the same. Because of this I have gone back to booting kernel 3.16.0-38-generic.

Thanks in advance for your support.

what does the following command spit out:

Code:
modinfo e1000e | grep version
Have you tried to reload like this:

Code:
modprobe e1000e EEE=0
Also have you tried to use Intel's driver?

lazydog,

Thanks for the quick reply and suggestion.

The output from the commands you suggested are as such:

Code:
# modinfo e1000e | grep version
version:        3.3.3-NAPI
srcversion:     BC7D8BD3880A3E5F62C57D7
vermagic:       3.16.0-38-generic SMP mod_unload modversions
and after running: modprobe e1000e EEE=0 ,
dmesg shows no change, but I still have this:

Code:
# lshw -numeric -C network

Thanks for the recommendation, jefro. Before checking the forums today, I decided to take the battery out of the laptop and let it sit for a few minutes and after putting the battery back in and booting up, the interface was there. I had tried powering off (even overnight), but not removing the battery, so it appears to have been an issue with the BIOS and not the adapter or the kernel module.

Thanks again for all of your help and suggestions. The issue is resolved.
