Description Dominik Gronkiewicz 2018-12-12 15:15:02 UTC 
After upgrading to F29, the wifi adapter would not show up anymore:

# nmcli device
DEVICE  TYPE      STATE          CONNECTION 
eth0    ethernet  połączono      eth0       
lo      loopback  niezarządzane  -- 

Clean install was suggested in #fedora-arm IRC, and after that the adapter would work under the original kernel (4.18.16-300), but the update to 4.18.18 or later would bring back old behavior (wifi not showing up). I did not mess with /lib/firmware/brcm/brcmfmac43430-sdio.txt file after clean install (like in fedora<=28) as it should work out of the box (https://fedoraproject.org/wiki/Architectures/ARM/Raspberry_Pi#Is_the_onboard_WiFi_and_Bluetooth_supported_on_the_Raspberry_Pi_3.3F).

Power management problems were also suggested in #fedora-arm (new scaling behavior drawing more power) but switching to dedicated power adapter did not change anything.

Please fix this, I cannot use my Pi for weeks now, and new updates do not bring any improvement :( I also use my Pi headless so I cannot manually select the oldest kernel while booting (unless there is a way to do so). Now I'm running the following kernel and the behavior is still the same:

# uname -r
4.19.6-300.fc29.armv7hl
Comment 1 Peter Robinson 2018-12-12 22:09:49 UTC 
This is a dupe and was documented in common bugs

*** This bug has been marked as a duplicate of bug 1652093 ***
Comment 2 Dominik Gronkiewicz 2018-12-12 22:23:29 UTC 
Apologies, I have read the docs long ago obviously, but I thought the existing bugs refer to RPi 3B+, while I run the older 3B version of RPi (as far as I'm aware of). I will try to install the test kernel and report if it helps.
Comment 3 Peter Robinson 2018-12-12 23:12:41 UTC 
it's the same on both devices. The details are in the other bug and when I have something to test it will be provided there (I won't be commenting again here). The problem is intermittent and hence not easy to "fix" because it's not consistently reproducible hence the reason it's still a problem.
Comment 4 Dominik Gronkiewicz 2018-12-13 01:29:29 UTC 
I tried the following line from "common bugs" document and it didn't install anything new. Is there a workaround for this problem? Unfortunately, I need wifi in my Pi and can't wait.

Didn't work:
dnf --enablerepo=updates-testing update --advisory=FEDORA-2018-cb49f8a11b

Thanks!
