CC'ing Sasha Neftin.

Also receiving this issue on my new build. Already reached out to ASUS about this error as well. The notorious I225-V bug has come back to haunt again.

Thanks for the reply. I added this parameter to my boot config, and I'm testing it now.
BR,

No problem Adam. I've been pulling my hair out about this (as well as many people all over the internet) over the I225-V bugs. 

ASUS got back to me and said it's "hardware failure" but in reality, it's a firmware failure. Try maybe swapping out your MOBO with the Hero version because people on Amazon have not been having issues with that board. Or just get a PCI ethernet adapter that's not based off the I225-v chipset. Best of luck.

Unfortunatelly IGC driver is still crashing :(

Hmm it's been OK so far for me... but I am swapping out the motherboard from Amazon because I don't trust this chipset. I haven't crashed on Ethernet. Here is my grub config:

Linux rei 6.0.7-gentoo-dist #1 SMP PREEMPT_DYNAMIC Tue Nov 8 03:41:12 EST 2022 x86_64 AMD Ryzen 9 7950X 16-Core Processor AuthenticAMD GNU/Linux

My /etc/default/grub has this:

GRUB_CMDLINE_LINUX_DEFAULT="pcie_port_pm=off"

Then I ran:

grub-mkconfig -o /boot/grub/grub.cfg

and that applies the new bootloader parameters. I would really like to hear what Sasha Neftin's input is -- knowing that she is way more intelligent than I'll ever be and could absolutely help point us in the direction on how to fix this bug. ;)

Mine /etc/default/grub has this line:
GRUB_CMDLINE_LINUX_DEFAULT="loglevel=3 quiet pcie_port_pm=off"

and grub.cfg has this line:
linux   /vmlinuz-linux root=UUID=cb1d4d5b-3600-49be-a58d-10d52195e45e rw  loglevel=3 quiet pcie_port_pm=off

After applying this new setting I left my PC running overnight and it was fine, but when I started my work this morning IGC crashed:(.

Hmm you seem to have the same parameters. 

Adam try this?

https://www.reddit.com/r/linuxhardware/comments/y2f3mf/igc_kernel_crashes_on_i225v_with_latest/

Intel engineers please help give an explanation as to what's going on!

IGC just crashed on me -- never mind! It's still borked with the PCI command in GRUB.

Swapped in a new motherboard (upgraded from the strix to the crosshair) and so far, not issues. Will update if I get a crash.

Thanks for your email, I am OOO on maternity leave.
You can contact me by Teams, but response might take some time.
For urgent issue, please talk to my manager shmuel.ben-nisan@intel.com.

Thanks,
Amir

Amir thank you for your response. I believe the reddit thread is in contact with intel engineer's but I will forward this. Great to see Intel treating their employees well with ML. Congratulations on your newborn!

Hello,
just to inform you :)
with the latest bios update from Asus (ROG STRIX X670E-F GAMING WIFI BIOS 0805) and
this kernel parameters: 
linux   /vmlinuz-linux root=UUID=cb1d4d5b-3600-49be-a58d-10d52195e45e rw  loglevel=3 quiet pcie_port_pm=off pcie_aspm.policy=performance

my IGC has stopped crashing. Currently I'm running my Pc about 32h straight.

BR,
Adam
