Try put pcie_aspm=off in the kernel boot line of grub.

You might try editing or creating a new file in /etc/modprobe.d called e1000e.conf and adding a line to that that


options e1000e IntMode=1,1

 Each 1 is for each NIC. Eg. If you have 2 e1000e NICs you need the above.

Another option to try is:

setpci -s 02:00.0 CAP_EXP+10.b=40 

setpci -s 03:00.0 CAP_EXP+10.b=40
