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, reason -52 [ 87.669940] brcmfmac: brcmf_set_channel: set chanspec 0xd02a fail, reason -52 [ 87.779964] brcmfmac: brcmf_set_channel: set chanspec 0xd02e fail, reason -52 [ 89.539921] brcmfmac: brcmf_set_channel: set chanspec 0xd090 fail, reason -52 [ 89.540316] brcmfmac: brcmf_set_channel: set chanspec 0xd095 fail, reason -52 [ 89.540653] brcmfmac: brcmf_set_channel: set chanspec 0xd099 fail, reason -52 [ 89.540985] brcmfmac: brcmf_set_channel: set chanspec 0xd09d fail, reason -52 [ 89.541326] brcmfmac: brcmf_set_channel: set chanspec 0xd0a1 fail, reason -52 [ 89.541662] brcmfmac: brcmf_set_channel: set chanspec 0xd0a5 fail, reason -52
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?
