Hi,
this is some kind of older issue with brcmfmac. Everytime i unload the
kernel module (e.g. v5.0-rc8 or next-20190301) on a Raspberry Pi 3
(multi_v7_defconfig / arm64_defconfig) after the driver has successful
probed, i'm getting such bogus error messages in the kernel log:
[ 870.477114] brcmfmac: brcmf_proto_bcdc_query_dcmd: brcmf_proto_bcdc_msg
failed w/status -5
[ 870.477122] brcmfmac: brcmf_cfg80211_get_tx_power: error (-5)
[ 871.057074] brcmfmac: brcmf_fil_cmd_data: bus is down. we have nothing
to do.
[ 871.057153] brcmfmac: brcmf_fil_cmd_data: bus is down. we have nothing
to do.
[ 871.057870] brcmfmac: brcmf_fil_cmd_data: bus is down. we have nothing
to do.
[ 871.057878] brcmfmac: brcmf_cfg80211_get_channel: chanspec failed (-5)
Is there a chance to remove or at least reduce them?
These are triggered by user-space. Upon remove we can not communicate with
the device, but have not yet removed the network interfaces. So when
user-space does a request we fail. I will have a look at it.
