The wifi failure is arch-specific. On rasbian wifi is functionally out of the box.
With new kernel 4.19.58-1 and firmware raspberrypi-firmware 20190715-1 wifi doesn't work even with my workaround. No wifi adapter is found anyway.
To reaload the driver takes no effect. Here is my dmesg dump:
after $this->bbcode_second_pass_code('', 'modprobe -r brcmfmac'):
usbcore: deregistering interface driver brcmfmac
after $this->bbcode_second_pass_code('', 'modprobe brcmfmac'):
cfg80211: Loading compiled-in X.509 certificates for regulatory database
cfg80211: Loaded X.509 cert 'sforshee: 00b28ddf47aef9cea7'
platform regulatory.0: Direct firmware load for regulatory.db failed with error -2
cfg80211: failed to load regulatory.db
brcmfmac: brcmf_fw_alloc_request: using brcm/brcmfmac43455-sdio for chip BCM4345/6
usbcore: registered new interface driver brcmfmac
brcmfmac: brcmf_sdio_htclk: HT Avail timeout (1000000): clkctl 0x50
Downgrading only the kernel took no effect. There is something missing in or wrong with the firmware database ...
what about PI 4

new situation:
I copied wifi-firmware files for brcmfmac43455* from https://github.com/RPi-Distro/firmware-nonfree/tree/master/brcm to /usr/lib/firmware/brcm/. After reboot wifi works with my workaround, to unload and reload driver, stable again.

I don't understand why the md5sum on brcmfmac43455-sdio.bin from that repo is different the one provided by linux-firmware.... also, we are not providing brcmfmac43455-sdio.clm_blob or brcmfmac43455-sdio.txt
The unload/reload workaround needs to be fixed long-term too. Did you try posting to the official RPi forums?

Didn't post it anywhere else yet. Seems to be only with arch. Got another PI 4 with raspbian, there wifi works fine right from the start.

Right, I'm saying ask for others to inspect the problem on Arch ARM as we help support the hardware. Perhaps there is something simple we can try. Since you are working on this WiFi issue, it makes sense for you to take the led. I am working on a Kodi package for Rpi4 now so have my hands full.
