Hi,

I'm on Lenovo T470s with Intel Corporation Wireless 8265 / 8275 ( rev 78 ) wireless card.

I've setup linux-firmware and I've update my kernel to 4.12.5-gentoo

The microcode fail on load :

Code:
# dmesg | grep -i -E 'iwl'

Nice!

It's works. :D

I've add in my kernel:
Device Drivers ---> Generic Driver Options ---> Fallback user-helper invocation for firmware loading (CONFIG_FW_LOADER_USER_HELPER_FALLBACK=y)

Thanks.
