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:

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

Thanks a lot,
