Comment 296 for bug 204996

@ kpagan, after copying the newly build driver module e1000.ko in /lib/modules/`uname -r`/kernel/drivers/net/e1000/

Did you re-build the initrd with the following?

sudo update-initramfs -u -k `uname -r`

You have to check that when you start the system, the correct module gets loaded at boot time.
You can check with ethtool -i <device>
The version should be 7.6.15.5-NAPI
