Hi guys,

let me answer to all of you here:

AFAIR, this happens when I stick the network cable in. I'll pay
attention to the exact moment when this happens in the future and report
back.

Yes. I normally run powertop when the machine goes up after a reboot and
set all tunables to "Good". The above is one of them.

Yes, as I mentioned, there is a very high chance that it happens when I
plug in the network cable. But I'll need to confirm that.

Not that I know of - the partner is a 8-port switch where other machines
are connected. Their connection is fine AFAICT.

Machine is Thinkpad x230, I'm attaching full lspci -vvv -xxxx output
with PCI config space dump, hth.

Thanks guys.
