[SOLVED] iwlwifi-7260-17.ucode isse with linux kernel 4.9

[libfab]

I have lately built and installed linux kernel 4.9 with no issue except for wifi support.
I own a motherboard equipped with the Intel wireless 7260 driver (id 808608b1)
I followed instructions given by the gentoo page on iwlwifi (https://wiki.gentoo.org/wiki/Iwlwifi)
I tried both module and in-kernel builds of the driver.
It did not work either way.
The cause seems to stem from driver versoning. On loading, the 4.9 kernel requests version 17 of the driver according to dmesg

>[ 5.315107] iwlwifi 0000:08:00.0: Direct firmware load for iwlwifi-7260-17.ucode failed with error -2

whilst eix says I can only install version 16

Description: Firmware for Intel (R) Dual Band Wireless-AC 7260

So the bottom line is please update the sys-firmware/iwl7260-ucode package to version 17.

Now before I send this request to maintainers, is there any forum member out there who may have found a better way out using portage as is?

Note : system was freshly sync'd with the the gentoo overlay on board.

libfab,

Welcome to Gentoo
The version you need is in linux-firmware. You will need to remove sys-firmware/iwl7260-ucode before you can install linux-firmware.
At least, they should be mutual blockers since they install at least some of the same files.

linux-firmware is rather large. You can customise what you will install after its installed.
I have version 20161005.

Thanks for replying so quickly.

It worked for me, using the latest 20161205 linux-firmware version (in-kernel build).

Aaaah yes. gentoo-sources version 4.9 is the latest ~amd64 version so it's only natural to use the latest ~amd64 linux-firmware version and update my old one.
So much for the noob

I have an identical issue after upgrading from 4.8 to 4.9. I am using sys-kernel/linux-firmware-9999 already though.

Any ideas?

I have the exact same error after updating to 4.9:

I don't think it's a bug. Newer kernels demand firmware to be injected in the kernel config and not set as a module:

For me the issue was solved by activating the driver via menuconfig. For some reason it got deactivated during the update and adding the old config back manually to .config did not work.

That is, it sufficed to activate: Device drivers -> Network dd support -> Wireless LAN -> Intel -> iwlwifi -> follow the warning msg that is displayed

Here is my current (working) diff (compare it to the last one):
