Wireless network disappears on Raspberry Pi 4B after kernel-default 6.0.12
Last modified: 2023-01-23 07:25:20 UTC
Created attachment 863687 [details] dmesg-6.1.1.log After upgrading kernel-default to 6.1.x for my rpi4 (running openSUSE Tumbleweed) from kernel:stable repo, I found my wireless network device (wlan0) was gone. Downgrading to kernel-default 6.0.12 fixes the problem temporarily. May that be a kernel-firmware issue as I suspect? dmesg logs are provided as follows.

Happy new year. Can you please provide the available firmware files on the rpi4 ls /lib/firmware/brcm/brcmfmac43455-sdio*

Yesterday i copied the brcm/cypress firmware to my Raspberry Pi OS sd card (mainline kernel, 32 bit, multi_v7_defconfig + CONFIG_FW_LOADER_COMPRESS), but i wasn't able to reproduce this issue with Linux 6.1. So issue seems to be more specific. I will look how to debug this.
armv7 does not seem to be affected. I tried kernel-firmware at versions 20221130 and 20221216 (updated 5 days ago in Factory) but there is no change. Kernel 6.1.0 received lots of updates for brcmfmac. I also tested 6.1.2 which had more fixes, but still no luck.
Could you try this pending fix: https://patchwork.kernel.org/project/linux-wireless/patch/20221230075139.56591-1-jisoo.jang@yonsei.ac.kr/
Thanks, Stefan, but this did not help. The WiFi interface still does not appear

As it is visible from the log clm_blob is not loaded in non-working case. FTR, Bluetooth is working fine in the new kernel.
Not sure if it related, but files which firmware tries to load are: Working case: brcmfmac43455-sdio.raspberrypi,4-model-b.bin brcmfmac43455-sdio.raspberrypi,4-model-b.txt Non-working case: brcmfmac43455-sdio.raspberrypi-rpi.txt brcmfmac43455-sdio.raspberrypi-rpi.bin This is on RPi 4B device.
@Ivan Thanks this helps a lot. It seems that the real board model (raspberrypi,4-model-b) has been overwritten by some bogus entry (raspberrypi-rpi). Since i'm testing without chain loading (no U-Boot, no EFI) this issue wasn't reproducible in my setup. Sorry, i don't have the time to bisect with this complex boot setup. But the following commits looks likely to cause the issue: 7682de8b335 wifi: brcmfmac: of: Fetch Apple properties 7cb46e72141 wifi: brcmfmac: firmware: Support passing in multiple board_types e263d722941 wifi: brcmfmac: firmware: Handle per-board clm_blob files
Yep, it was this one [1]. Fix send upstream [2]. Stefan, sorry, I forgot to add you to the CC list. [1] 7682de8b335 wifi: brcmfmac: of: Fetch Apple properties [2] https://lore.kernel.org/all/20230106072746.29516-1-iivanov@suse.de/
Same problem on the PinebookPro, downgrading to kernel-default 6.0.12 also works.
(In reply to Ayers from comment #15) > Same problem on the PinebookPro, downgrading to kernel-default 6.0.12 also > works. Same issue. Fix was merged in netdev/net.git. Hopefully it will land soon in kernel-source::stable. https://lore.kernel.org/netdev/CALeDE9M_AOs_hMdjBtFCYGXXMQzZ-uXK=x8=19GruC+UQN1ESg@mail.gmail.com/T/
The fix is in 6.2-rc4, but not backported in stable 6.1.6 yet. Do you know what the plans are for stable?
This is what I have from Greg: Date: Sat, 14 Jan 2023 11:03:31 +0100 This is a note to let you know that I've just added the patch titled brcmfmac: Prefer DT board type over DMI board type to the 6.1-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: brcmfmac-prefer-dt-board-type-over-dmi-board-type.patch and it can be found in the queue-6.1 subdirectory.
PATCH 6.1 020/183] brcmfmac: Prefer DT board type over DMI board type In stable review queue.

Just for reference, kernel-default 6.2-rc4 (which includes the patch by @Ivan and tested fixes the problem) has been uploaded to openSUSE kernel master branch on Jan 17: https://download.opensuse.org/repositories/Kernel:/HEAD/ARM/aarch64/kernel-default-6.2~rc4-2.1.g6bd4e43.aarch64.rpm https://github.com/openSUSE/kernel-source/commit/b1ecb39635ba2d65e33c44ef2eadd8cc078cd97d For users eagerly waiting for the fix, you can now switch to kernel master branch by following the instruction here: https://kernel.opensuse.org/master.html I guess we can close the issue once the patch gets backported to stable. Thanks for all you guys' awesome work.
