Re: [EXT] Re: [Intel-wired-lan] Intel I350 regression 5.10 -> 5.14 ("The NVM Checksum Is Not Valid") [8086:1521]

What messages are new compared to the working Linux 5.10.59?

I've uploaded the full boot logs to https://dev.gentoo.org/~dilfridge/igb/
(both in a version with and without timestamps, for easy diff).

* I can't see anything that immediately points to the igb device (like a PCI id etc.) before the module is loaded. 
* The main difference between the logs is many unrelated (?) i915 warnings in 5.10.59 because of the nonfunctional graphics.

The messages easily identifiable are:

Any advice on how to proceed? Willing to test patches and provide additional debug info.

Without any ideas about the issue, please bisect the issue to find the 
commit introducing the regression, so it can be reverted/fixed to not 
violate Linux’ no-regression policy.

I'll start going through kernel versions (and later revisions) end of the week.

Thanks a lot,
Andreas
