Linux e1000e (Intel networking driver) problem with resume and pcie=off [closed]
Solution 1:
Looks identical to this might. It does indeed appear to be an upstream bug. Check changelogs related to the e1000 driver, see if there's a patch you can back port or at least point the ubuntu kernel team to it. Try to bring your eth0 down, modprobe -r the driver before suspending, see if that's a potential work around. It may help upstream driver maintainers zero in on the bug.
