[e1000-devel] I210 failing during probe (probe of 0000:0a:00.0 failed with error -2)

[Sam S. <sam...@gm...>]

Hi Folks,

Can someone provide guidance on why igb probe failed? It is not clear by
code walk why igb_probe
<https://opengrok-evo.juniper.net/source/s?refs=igb_probe&project=ker-linux-v5.15-unified>()
is failing and returning -2.
