Hello everyone,
A while ago I was getting "The NVM Checksum Is Not Valid" message and no
ethernet access but I solved it following the instructions here:
http://mynixworld.info/2012/12/05/e1000e-the-nvm-checksum-is-not-valid/
Today, my laptop booted with a new message:

I took a look at /etc/udev/rules.d/70-persistent-net.rules and found:
# PCI device 0x8086:0x109a (e1000e)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*",
ATTR{address}=="00:08:00:00:00:00", ATTR{dev_id}=="0x0", ATTR{type}=="1",
KERNEL=="eth*", NAME="eth0"
# PCI device 0x8086:0x109a (e1000e)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*",
ATTR{address}=="00:40:00:00:00:00", ATTR{dev_id}=="0x0", ATTR{type}=="1",
KERNEL=="eth*", NAME="eth1"
Which shows that my MAC address has somehow changed once before it got stuck on
"00:00:00:00:00:00". Is there any way to reset my MAC address so I can use
ethernet again?
My laptop is a Lenovo Thinkpad T60. Below is the relevant output of lspci -vv:
