I'm trying to install Linux on Precision 7560 (that's why I bought it).
Unfortunately, the network card (Intel I219-LM) doesn't work.
The kernel driver loading is aborted and a message is displayed:

e1000e 0000:00:1f.6: The NVM Checksum Is Not Valid

I have checked on the Internet and some people had the same issue.
I tried to follow their instruction but it didn't work. I gave up as
I do not want to brick the NIC.
I can not use WIFI to install the compiler and all required tools
to compile a custom e1000e, as the install image doesn't contain
the newest firmware and WIFI doesn't work. I cannot install the newest
firmware as the network card is flawed.

This is definitely a hardware problem. I bought my laptop in October and
this is my third hardware problem with a £ 2,500 laptop. Yes, I bought
the cheapest version should work.
I would be grateful for your help in solving this problem so that I could
finally enjoy my purchase.

BTW, Windows ignores the error, so the card works and the system does not
complain about an EEPROM checksum error.

Many thanks
Marcin
