Description:

After upgrading linux and linux-firmware, loading iwlwifi produces the following messages to dmesg. Trying to bring the wifi interface up also fails.

[Tue Oct 23 07:17:12 2018] iwlwifi 0000:3a:00.0: loaded firmware version 36.7596afd4.0 op_mode iwlmvm

[Tue Oct 23 07:17:13 2018] iwlwifi 0000:3a:00.0: Failed to run INIT ucode: -110

Broken versions:
* linux 4.18.16-arch1-1
* linux-firmware 20181018.d877533-1


After downgrading to older versions, it started working again with this in dmesg output:

[Tue Oct 23 07:28:51 2018] iwlwifi 0000:3a:00.0: enabling device (0000 -> 0002)
[Tue Oct 23 07:28:51 2018] iwlwifi 0000:3a:00.0: loaded firmware version 36.e91976c0.0 op_mode iwlmvm
[Tue Oct 23 07:28:51 2018] iwlwifi 0000:3a:00.0: Detected Intel(R) Dual Band Wireless AC 8265, REV=0x230
[Tue Oct 23 07:28:51 2018] iwlwifi 0000:3a:00.0: base HW address: 00:28:f8:87:a2:e9

Not sure if this is the last working combination, but at least these work:
* linux 4.18.3.arch1-1
* linux-firmware 20180815.f1b95fe-1

I'm happy to provide more info!
This task depends upon

Downgrading linux-firmware is enough to make it work again, linux 4.18.16-arch1-1 is fine.

I've been noticing this too, but it works at first, then sometimes cuts off randomly (so it took me a bit to realize I was having problems). wpa_supplicant logs this error:

Is it also an issue for 4.19 and has upstream linux-wireless been notified?

Having used the older firmware until now, I reported this to the linux-wireless mailing list today. After getting a reply [1], I tested again with the new firmware and now it seems to work. So, at least for me, this issue resolved itself.

Hello.

The issue started to appear at my system during this april/may. I don't remember whether linux-firmware was recently updated though.
My linux kernel is: 4.19.46-1-lts
My linux-firmware is: local/linux-firmware 20190514.711d329-1
My card is: 01:00.0 Network controller: Intel Corporation Wireless 8260 (rev 3a)

Attached the error messages. (I don't have any special setup on my laptop, no dual boot as well)
