E1000e green0 - Detected Hardware Unit Hang

The cards you have mentioned don’t use the e1000e driver, they use the igb driver. This is a driver/hardware bug, and OP has indicated in the title that it’s about the e1000e driver.

You all should go hang out in the kernel.org bugzilla instead.

Do note that this was reported in 2012.

The e1000e, or at least some hardware revisions using that driver, is buggy under Linux since, like, 10 years. It won’t be fixed in ipfire, it can’t be fixed in ipfire, it must be fixed upstream. Swap out your network cards.

(btw if this reappeared in 158 it’s likely because of the linux-firmware 20210511 that was in that update, but it doesn’t matter, as e1000e has been more-or-less broken since ten years, and hunting this bug downstream is a fool’s errand. It must be fixed upstream. It hasn’t reliably been fixed upstream for ten years. Do the math)
