Users reported that X1 Carbon 7th can only suspend once due of "e1000e 0000:00:1f.6 enp0s31f6: Hardware Error"  .
I managed to get one at hand and I can confirm the issue is 100% reproducible.
The error occurs at the first e1e_rphy() in e1000_copper_link_setup_82577() .
Reverting "e1000e: Add support for S0ix" makes suspend work again.
I also tried commit e1738282f6c6 "e1000e: fix S0ix flows for cable connected case" however the issue persists.
