Public bug reported:

On the noble server release candidate image testing, I noticed that the
automated wifi tests we run for certification were passing, but they
logged some errors from dmesg related to brcmfmac. The log is filled
with lots of these errors:

kern  :err   : [Wed Apr 24 11:19:12 2024] brcmfmac: brcmf_set_channel: set 
chanspec 0x100c fail, reason -52
kern  :err   : [Wed Apr 24 11:19:12 2024] brcmfmac: brcmf_set_channel: set 
chanspec 0x100d fail, reason -52
kern  :err   : [Wed Apr 24 11:19:12 2024] brcmfmac: brcmf_set_channel: set 
chanspec 0x100e fail, reason -52
...

To be clear, it was able to get a wifi connection, but something seems off with 
this. 
I've noticed this on rpi4 and rpi5 so far, not sure about others yet
