Hi.
So, there was bios update. Unfortunately, it did not solve this issue.
Also, i did test latest 3.0.4.1, and it suffers from this bug also.
Patch now looks slightly different:
--- e1000e-3.0.4.1.orig/src/ich8lan.c 2014-02-26 09:22:44.000000000 +0100

Any estimation when this will be finally solved? Who i need to contact
to (help me) solve this?
