Dear Maintainer,

5GHz WiFi stopped working with 20210208-4.
iw wlan0 scan does not show SSID of 5GHz WiFi.
With 20201218-3, 5GHz worked fine,
provided that vc4.ko is blacklisted (see #981616).

I will see if the newer package in the experimental
behaves differently.

please provide info on the affected hardware,
also using apropriate bug levels would be nice.

please show affected dmesg output working and non working,
the difference between 20210208-3 20210208-4 is minimal,
hence it should be easy to find out what broke?

thank you for your report + kind regards,

Hi Maximilian, thank you for your attention!

It is Raspberry Pi 4B 8GB model.

Not at all, unfortunately.
20210208-3 was completely broken on RPi4B as
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=984489
20210208-1 to 20210208-3 were broken...
The last working version was 20201218-3, and I apt-mark-holded firmware-brcm80211.
I unhold it in the weekend and found this issue.

I attach dmesg of 20201218-3, 20210208-4, and 20210315-1.
It was also interesting that installation of 20210315-1 causes boot failure
and showed "Give root password for maintainance"...
Should I file a separete report against 20210315-1?
20210315-1~exp1 was booted fine...

Best regards, Ryutaroh

please excuse my ignorance first, but are you sure that these
bootflags are still adequate for the latest cypress firmware?

concerning bluetooth unfortunately this seems missing firmware
in latest upstream firmware git (see #962038 ) or possible wget info
https://wiki.debian.org/RaspberryPi4#Bluetooth

this should not be reproducible as 20210315-1 and 20210315-1~exp1 are
unchanged (just uploaded into experimental before unstable).
 
Thank you for your report!

Hi Maximilian, thank you again for your response.

What did you mean by "bootflags"??
Did you mean /proc/cmdline (i.e. cmdline.txt in Raspberry Pi)?

I know that bluetooth interferes with 2.4GHz WiFi with pure Debian
packages as reported in
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=984844

I do not see any intererence between bluetooth and 5GHz WiFi.
I doubt the intererence as bluetooth frequency does not overlap with 5GHz WiFi at all.
With the firmware 20210208-4, 2.4GHz WiFi works fine provided that
bluetooth is turned off by rfkill etc.

I am running a combination of pure Debian packages and
encountered the reported symptom. What is a Debian way to
use 5GHz WiFi? Do you need additional information?

I will re-check 20210315-1.

The system boots with 20210315-1 and the reported symtom remains in
the same way. Ryutaroh

I also tried brcmfmac43455-sdio.clm_blob with a version from raspberry,
but with the firmware-brcm802111:20210315-3+rpt3 the Rasperry P4b debian
bullseye stopped working. I then went back to the version
http://raspbian.raspberrypi.org/raspbian 20210315-3 and with that the
wifi works again. It was not to be brought with 20210315-3+rpt3 to the run.

I likewise found that stealing just cyfmac43455-sdio.clm_blob (which
brcmfmac43455-sdio.clm_blob is a symlink to on my system) from
20210315-3+rpt3 and reloading the driver made everything happy and

One more addendum - just the clm_blob alone from
https://github.com/RPi-Distro/firmware-nonfree/commit/dc406650e840705957f8403efeacf71d2d7543b3,
not even the sdio.bin with it, on top of the stock bullseye
firmware-brcm80211, works for me.
