Another possibility is a Firmware issue, but Im just making guesses at the moment without the device in hand.
If you dual boot windows windows may have grabbed the device and wont let it go. Ive had it do that for NICs and Wifi on peoples machines. which makes them not work in linux till booting into windows again and shutting down but probably not that due to the old iso working.
@ricklinux Im finding a few other reports around online of people needing to disable ASPM for their Intel i211 NICs idk for sure but it wouldnt hurt to see if its enabled for Asus folks and to disable it and see if it helps them.
Well if @avgdd would try that on the latest ISO would be really helpful to answer that question because it seems to be these boards and that particular NIC.
@ricklinux still looking around regarding the i211, looks like some more issues over on opensense related to power management on the i211. Im getting more convinced this is an ASPM issue lol. Maybe i can enable it on my system and see if it craps out
EDIT: i tried it, no issues on my end at least with L0 & L1 ASPM. No issue with Firmware either. Its something Asus specific very obviously
For what is worth, you could copy the terminal output as text and paste it into your reply using </> button to format. This makes it searchable from a search engine and therfore more useful for other users looking for solution to similar issue.
It always seems to be those Asus ROG boards. Iāve looked at the manual. Itās typical except the part thatās odd and doesnāt make any sense is the csm mode.
They are basically saying itās best left in auto mode. They contradict themselves in saying enabled to support non UEFI driver add-on devices or Windows UEFI.
Then they say disabled to support non UEFI driver add-on devices or Windows UEFI mode.
These two statements contradict each other and donāt add up.
It sayās auto mode: The system automatically detects the bootable devices and the add-on devices.
So i would leave that it auto mode. APM has not much. Itās like mine ERP mode enable or disabled. I think itās disabled by default.
thats always the fun part about Realtek NICs, they āshouldā work. My Server has 2 x R8168 that are supposed to work with the kernel driver but they dont gotta use the dkms for them
