kernel 5.5.xxx not working with wireless

English Network/Internet
1

I am running Tumbleweed on an HP laptop. I ran “zypper dup” for edition 02072020 and my NetworkManager could not find my wireless adapter and, hence, my networks. The only thing it saw was Bluetooth. Fighting off panic, I downloaded the latest Tumbleweed install image on another computer with the intention of updating the problem away but when the install tried to find a network adapter, it could not. I have since done zypper dup daily and noticed that the kernel is being updated with disturbing regularity But nothing after 5.4.xxx will find the wireless doo hickey. In fact, the last two versions of 5,5,xx will not even load on my machine! I have to boot with 5.4.xxx to get online.

I am just curious and will try zypper dup on a few of my machines just to see what shakes out vis-a-vis wireless connectivity.

Since I have a workaround, I do not consider this critical but I am curious what broke and when it will be fixed. I have not dissected the boot logs, yet, but like I said, I can make the machine work so it is a low priority for me, just a pain in the butt!!!

Here is the journalctl -grep=iwlwifi output for a 5,4.xxx boot fo;;owed by the same for a 5,5,1.xxx boot:

Now, I ain’t no LINUX guru but it seems to me that the iwlwifi driver is blowing up…

This upstream bug report suggests that this problem may have been patched already in kernel 5.5.3.

https://bugzilla.kernel.org/show_bug.cgi?id=206333

Suggests that if you can live with your workaround, you should be seeing this kernel pushed to you automatically within a few weeks.

Getting “Failed to run INIT ucode: -110”.

Since wired NW works, what do you recommend? Wait for next update or try https://gitlab.com/emrose/xps13-7390_debian/issues/5#note_240886447?

Seems related to https://bugzilla.kernel.org/show_bug.cgi?id=205719

Based on the error

Direct firmware load for iwlwifi-Qu-b0-hr-b0-50.ucode failed with error -2

I grabbed the file from chromiumos/third_party/linux-firmware - Git at Google (as described in https://gitlab.com/emrose/xps13-7390_debian/issues/5#note_240886447?)


git clone https://chromium.googlesource.com/chromiumos/third_party/linux-firmware chromiumos-linux-firmwarecd chromiumos-linux-firmware
sudo cp iwlwifi-Qu-c0-hr-b0-50.ucode /lib/firmware/
cd /lib/firmware
sudo ln -s iwlwifi-Qu-c0-hr-b0-50.ucode iwlwifi-Qu-b0-hr-b0-50.ucode

Rebooted and all works.

I’ve seen posts elsewhere that say the fix is due to land in kernel 5.6

I followed the chromium suggestion but still didn’t work. Rolled back for now (thank god for that!), and will wait to see if it’s fixed in 5.6…

That is broken in kernel 5.6, so wait for an Update:

Ha, thanks! Hopefully 5.6.2 then… Linux 5.6.2 Released With Fix For The IWLWIFI Intel WiFi Driver - Phoronix
