[SOLVED] Broadcom WiFi Broken After Upgrade Yesterday

walkingstickfan · 2022-08-24 07:45:36

Logged back into my Arch install after using Debian Stable and WiFi wasn't available. There isn't even an option in the NetworkManager Applet to use WiFi. Results of upgrade show no issues in the DKMS process of integrating Broadcom driver (?) into the kernel:

:: Running pre-transaction hooks...
(1/2) Removing linux initcpios...
(2/2) Remove DKMS modules
==> dkms remove --no-depmod broadcom-wl/6.30.223.271 -k 5.15.60-1-lts
==> dkms remove --no-depmod broadcom-wl/6.30.223.271 -k 5.19.1-arch2-1
==> depmod 5.15.60-1-lts
==> depmod 5.19.1-arch2-1

...

You want to look at "ip a", "rfkill" and "dmesg" and check whether the situation is the same w/ the main and lts kernel.

and rebooting, "journalctl --system" shows the module (wl from broadcom-wl-dkms 6.30.223.271-33) is simply not loaded into the kernel:

Aug 24 12:34:31 box kernel: BPF: [112816] ENUM rpm_status 
Aug 24 12:34:31 box kernel: BPF: size=4 vlen=5
Aug 24 12:34:31 box kernel: BPF:  
Aug 24 12:34:31 box kernel: BPF: Invalid btf_info kind_flag
Aug 24 12:34:31 box kernel: BPF: 
Aug 24 12:34:31 box kernel: failed to validate module [wl] BTF: -22

But it doesn't stop there: Every DKMS module is affected - in my case wl, facetimehd and all three vbox* modules.

Rolling back the kernel or gcc didn't change that behavior.

Can you "modinfo wl"?
What if you "depmod -a"?

Thx - after the pahole downgrade to 1.23 I had to rebuild the DKMS modules and now they work again.

Issue exists with the current version (as of 08/23/2022) of both kernels.

walkingstickfan · 2022-08-25 06:56:03

Hmmm...I downgraded pahole to 1.23, then:

01) rebuilt all modules for the currently running kernel (LTS), which didn't display anything
02) rebuilt the Broadcom module for the currently running kernel (LTS) (don't remember the output)
03) Rebooted; still no WiFi access
04) Ran the following commands, both of which stated that the Broadcom module was already installed:
04a) dkms install --no-depmod broadcom-wl/6.30.223.271 -k 5.19.3-arch1-1
04b) dkms install --no-depmod broadcom-wl/6.30.223.271 -k 5.15.62-1-lts
05) Rebooted

And I still have no WiFi access. Editing connections via the NetworkManager applet does show the WiFi connection entry I made when I installed Arch, but left-clicking on the Network Manager applet does not show a WiFi entry.

If you didn't issue a "dkms remove" command you probably still have the old modules installed.

Try

dkms remove broadcom-wl/6.30.223.271 --all

followed by

dkms install broadcom-wl/6.30.223.271 --all

Thanks, I'll give it a try, although it appeared that the modules were removed during the upgrade; reference my OP.

Your removal command worked, but the --all parameter is not allowed for the install option. I had to install the Broadcom driver individually for both kernels.
