Bug ID: 198047
Summary: Regression in e1000e with kernel 4.14.3
Product: Networking
Version: 2.5
Kernel Version: 4.14.3
Hardware: x86-64
OS: Linux
Tree: Mainline
Status: NEW
Severity: normal

I got a regression with my network interface e1000e.
With kernel 4.14.3 and Fedora 27 the network interface e1000e doesn't come up
if I set MTU to 1492 and boot with that settings.
with MTU set to auto sometimes the interface is active and sometimes not.
In network manager (Fedora 27) the button to activate/deactivate the network
interface is greyed out. Computers backside network LED'S are off.
there are no errors in the logs nor selinux issues, ...
up to 4.13.2 all kernels from 4.13 series I got no errors.
how can I debug this ?
Maybe from interest:
with the late Fedora 27 Beta (I believe kernel 4.12.x) I remember issues
switching interface MTU from auto to 1492.
