Hello,
I've noticed that there's a bug in the Ubuntu 24.04 Linux kernel driver in for the I226-V ethernet controller. The device crashes, when a user tries to utilize power management capabilities of the hardware.
The devs of popular power management tool powertop has also acknowledged this bug on Github. Same for the manufacture of the Odroid H4 devices.
There's an open bug report from February 2024 over on Bugzilla referring to the same issue, but it has yet to be fixed.

Hi TOMillr,
Good Day!
As you confirmed the ethernet controller is embedded on the board, there may be custom BIOS and drivers from the OEM/Manufacturer. Hence we kindly request you to contact the OEM/ Manufacturer as they are best equipped to troubleshoot your issue.
Thank you for your understanding.
Regards,
Simon

Thanks for the suggestion, I have to contradict you however.
The issue exists across multiple boards made by different manufacturers and is caused by the official driver that ships with the current Linux kernel. It seems to happen on ALL boards that use two or more ethernet ports I226-V ethernet controller.
I've already spoken to OEM/manufactures like Hardkernel or Asus as well as the maintainer of the powertop power management utility and they all point the finger back to the official Intel driver. That's why I've referenced the bug report over on Bugzilla in my initial post, which so far has gone unnoticed.
