Iwlwifi issue

onyxnz · June 18, 2020, 9:59am

Anybody else having total lockups with Wifi, when running iwlwifi? Just tonight this started, with total lockup after about 5 minutes, regardless of DE, only when on Wifi.
The only thing I can find in my journal is this:

It may be a firmware issue.

lspci -k

dmesg | grep firmware

You could try a new firmware. This was just updated yesterday but like to see the output here first to see what Intel chip it is and what module it’s using.

The firmware for iwlwifi is here.

Okay so this is a very new Intel Wifi chip

Intel Corporation Wireless-AC 9560 [Jefferson Peak] (rev 10)

It is using the iwlwifi module which is correct.

 firmware version 46.8902351f.0 9000-pu-b0-jf-b0-46.ucode op_mode iwlmvm

I know there is an issue with the Jefferson Peak chip but i need to look some stuff up.

Edit: I’ll be back hopefully with some info.

ricklinux · June 18, 2020, 9:28pm

Do you have encrypted connection turned off? Maybe that is the issue. Instability!

Edit: If this doesn’t work maybe you could try the updated firmware.

onyxnz · June 18, 2020, 9:51pm

Didn’t work; did as you said, rebooted, enable wifi, open terminal to ping google.com ,and got through 8 ping responses before total lockup.
Now that linux-firmware-iwlwifi-git is older than the linux-firmware I have installed ( 20200519.8ba6fa6-1 which also brings in a bunch of other firmwares)…should I be replacing one for the other?

ricklinux · June 18, 2020, 9:52pm

I’m not really sure on that maybe you ought to leave that.

onyxnz · June 18, 2020, 9:54pm

Thanks for the help anyway, @ricklinux !

ricklinux · June 18, 2020, 9:56pm

Does it lock up the whole computer? How do you get out of it?

onyxnz · June 18, 2020, 9:57pm

Yeh, solid lock. Power off is only exit.

You have the latest firmware installed. I think i would go back one to the previous version. This is the previous version.

https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/

iwlwifi-9000-pu-b0-jf-b0-43.ucode

You have iwlwifi-9000-pu-b0-jf-b0-46.ucode

Edit: Do you know how to do that?

Rebooting now…

onyxnz · June 18, 2020, 11:12pm

And that is the fix!

Also, for any other poor slobs trying to get a handle on this, you will need to add:

IgnorePkg   =intel-ucode

to /etc/pacman.conf after this, so that there is no automated updating back to the broken firmware.

EDIT: Bugger… it lasted longer, but locked up straight after being able to post this !!!

ricklinux · June 18, 2020, 11:14pm

So it is caused by an updated Intel-Ucode? Did you find some other info on it?

Edit: I think you misunderstood me. The intel-ucode is related to the cpu for boot up process and security. What i was referring to was the iwlwifi firmware for your wireless chip. The previous version is actually in /lib/firmware. You just have to get it to use that one?

onyxnz · June 18, 2020, 11:17pm

Going to try a further roll back…

onyxnz · June 18, 2020, 11:28pm

So my dmesg is being spammed by this

[   68.683236] iwlwifi 0000:00:14.3: Unhandled alg: 0x707

Which leads me to this:
https://bugzilla.kernel.org/show_bug.cgi?id=203593

Something to do with firmware versus access point?
At this stage intel-ucode 20200520 is working, for longer than anything else has…

onyxnz · June 18, 2020, 11:33pm

OH I C…so I am playing with the wrong file…so if I have the old firmware in place in /lib/firmware, then how do I tell it to use that rather than the new one?

ricklinux · June 18, 2020, 11:35pm

This is happening with the current iwlwifi firmware which is iwlwifi-9000-pu-b0-jf-b0-46.ucode
You need to try the previous firmware which is iwlwifi-9000-pu-b0-jf-b0-43.ucode
It is on the system in the /lib/firmware folder.

I’m not entirely sure how to make the change .
