iwlwifi problems, maybe firmware related?

[Randy Dunlap]

Hi,

When I boot 5.16 or 5.17-rc1, I get messages like:

Can anyone tell what's going on here?
Is it just firmware version problem?
Any suggestions/ideas?


This is openSUSE Tumbleweed (rolling updates) on a Dell Inspiron 15.
I don't know how new or old this problem is since I just got the laptop
and I haven't used anything older on it.

thanks.

We see nothing but crashes with the version 67 firmware.  Remove that
from your /lib/firmware/ dir (and make sure version 66 or lower is there),
and reboot and it should work again.

Thanks,
Ben

Well. Yes, that does make things work for me.

It's odd, though, that openSUSE Tumbleweed with kernel "Linux version 5.16.1-1-default"
(whatever that is) also works with no problems.

Thanks for your help.

This is because of broadcast filtering.  This feature hasn't been
supported for quite a while and now the firmware rejects the command we
send to it.

The easy fix is to compile iwlwifi without
CONFIG_IWLWIFI_BCAST_FILTERING (which should not be enabled by
default).

I have removed this option from the driver now and will send the patch
to 5.17-rc* as a fix.

Golan, I think we have a bugzilla for this, do you remember?

Just confirming that kernel 5.16 without broadcast filtering works
with firmware v67.

Yes, please.

Great, thanks for the confirmation!

Just out of curiosity.  How did you end up with broadcast filtering
enabled? Is it a default configuration from some distro?

Nope.  I didn't know that it was not supported so I enabled it.
