    Code:
    lsmod | grep -i e1000
    As I put the commands in, there is no output in the terminal. lsmod gives this, both BEFORE AND AFTER kernel updating (no change):

    Code:
      	 	 	 	  
    lsmod | grep -i e1000 e1000e 286720 0

    Default AW: No network after kernel update

    I would write a bugreport.

    I did just that: Bug 1191663 on https://bugzilla.opensuse.org/show_bug.cgi?id=1191663 . Thanks for your good guidance!

    This seems to be the culprit ...
    It's actually a regression by the kernel patch
    patches.suse/e1000e-Do-not-take-care-about-recovery-NVM-checksum.patch
    This patch is documented here:
    https://bugzilla.kernel.org/show_bug.cgi?id=213667
    Because of this patch, my machine gives an NVM checksum error, and the driver corrected it in the past, while this isn't done any longer and treated as a fatal error now.
    Let's hope it will get fixed soon!

    BEFORE that patch was introduced into the kernel, this is what DMESG says about e1000e, when the network is there:
    [ 4.937015] e1000e: Intel(R) PRO/1000 Network Driver - 3.2.6-k

    And AFTER the patch was introduced in the new kernel, I have NO NETWORK and DMESG says this about e1000e:
    [ 4.734542] e1000e: Intel(R) PRO/1000 Network Driver - 3.2.6-k
    [ 4.734543] e1000e: Copyright(c) 1999 - 2015 Intel Corporation.

    [...]
    [ 5.061273] e1000e: probe of 0000:00:1f.6 failed with error -5

    So THAT is the problem that has to be solved ...

    My search engine gives: http://mynixworld.info/2012/12/05/e1...-is-not-valid/

    Maybe the new driver did become more strict on checking the NVM Checksum.

    Default Re: No network after kernel update

    Indeed, since this new patch was introduced to mitigate the effects of a Dell computers failure where nvm checksum calculating slowed down the boot process, I suddenly get this message and NO NETWORK with this new kernel. It's a brand new computer, no Dell at all, bought specially and only for use with Linux. It's an Intel motherboard, while all my other computers are AMD.
    So THAT is the problem that has to be solved ...

    1. Can the patch be rewritten?
    2. Or can a kernel parameter be designed for booting?
    3. Must the EEPROM be corrected somehow?
    4. Must Intel's e1000e driver be renewed?
    5. Or is there another method to avoid the network failure?

    I suppose - or rather, I hope - that a solution is being researched “higher up”. But maybe there is a faster road? Because IF NOT, I am stuck for eternity without any kernel updates nor system version updates ...

    I read about a suggestion that I should enter UEFI-BIOS utility, enter ADVANCED MODE, and enable ADVANCED NETWORK STACK CONFIGURATION and then booting up; this should somehow clear the bad NVM checksum; and then I could go back to the BIOS and disable the network stack.
    But I am hesitant: don't I risk jeopardizing my whole network card that way? Is there somebody who can give me good advice in these matters? THANKS ALREADY!

    Is the Ethernet integrated or is it a separate card?

    If it is a separate card I would consider replacing it by another one.
    If it is integrated, I would bite the bullet and follow the process in the link I posted to fix it.

    Wait for the answers in your bugzilla.
