Hi,
almost one year ago, i reported [1] about annoying log messages from
brcmfmac. After commit "wifi: brcmfmac: avoid handling disabled channels
for survey dump" [2] the periodic messages disappeared, which is great.
Unfortunately there is a different scenario, which still trigger them at
least on the Raspberry Pi 3B+ (arm/multi_v7_defconfig). I tested Linux
6.3, 6.6 and recent mainline.
Used firmware:
Firmware: BCM4345/6 wl0: Jan 4 2021 19:56:29 version 7.45.229 (617f1f5
CY) FWID 01-2dbd9d2e
Scenario:
- start Raspberry Pi 3B+ with graphical interface
- wpa_supplicant successful connects automatically to WPA2 network
- disconnect from WPA2 network (no brcmfmac error messages until now)
- re-connect successfully to WPA2 network again (trigger error messages
once)
Example output from current mainline:
[ 87.449903] brcmfmac: brcmf_set_channel: set chanspec 0xd022 fail,
reason -52
[ 87.559928] brcmfmac: brcmf_set_channel: set chanspec 0xd026 fail,

Again look like these are disabled channels. At least chanspec 0xd022
is 5G channel 34. You say you get this only once so not every 60 seconds?
I get this everytime i trigger a reconnect to the wifi network, so not
periodically (checked that). Strangely the initial automatic connect
doesn't trigger this errors.
