Maybe you have a different card... IBM/Lenovo inserted "equivalent"
cards (for windows) but it may not be iwi or the same revision.
I believe on certain ThinkPads I inserted a compatible card coming from
a Dell or HP system. Just doen't have IBM/Lenovo BIOS so it needs the a
patch not to blame on 1802 error...

It is a bad error I think. I rebooted and started X, no issues. I did
not configure network.

I have the gut feeling that... network disturbs video!
Being Intel WiFi and Intel Video... need to confirm this and maybe
testing wired vs wireless.
