 Posted: Mon Sep 30, 2013 6:23 am Post subject: [SOLVED]: Help needed with cfg80211 spamming logs |
 |
|
Hi, since upgrading from gentoo-sources-3.8.13 to 3.10.7-r1, my logs have been spammed with this every 3-5s:
| Code: | kernel: cfg80211: Calling CRDA for country: 97
kernel: cfg80211: Calling CRDA to update world regulatory domain
kernel: cfg80211: World regulatory domain updated:
kernel: cfg80211: (start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp)
kernel: cfg80211: (2402000 KHz - 2472000 KHz @ 40000 KHz), (300 mBi, 2000 mBm)
kernel: cfg80211: (2457000 KHz - 2482000 KHz @ 40000 KHz), (300 mBi, 2000 mBm)
kernel: cfg80211: (2474000 KHz - 2494000 KHz @ 20000 KHz), (300 mBi, 2000 mBm)
kernel: cfg80211: (5170000 KHz - 5250000 KHz @ 40000 KHz), (300 mBi, 2000 mBm)
kernel: cfg80211: (5735000 KHz - 5835000 KHz @ 40000 KHz), (300 mBi, 2000 mBm)

This is on a Thinkpad T420 with Centrino Advanced-N 6205 AGN wireless card, using the iwlwifi driver.
The wireless connection still seems to work, which distinguishes it from many similar reports on the web that I've seen.
/etc/modprobe.d/cfg80211.conf contains:
| Code: | | options cfg80211 ieee80211_regdom=UK |
/etc/conf.d/net contains:
| Code: | modules="!iproute2 !iwconfig"
modules_enp0s25="dhcp"
modules_wlp3s0="wpa_supplicant"
config_wlp3s0="dhcp"
dhcp="release"
wpa_supplicant_wlp3s0="-Dnl80211" |
/etc/wpa_supplicant/wpa_supplicant.conf contains:
| Code: | ctrl_interface=/run/wpa_supplicant
ctrl_interface_group=wheel
ap_scan=1
country=GB
network={
ssid="............."
scan_ssid=0
psk="..............."
priority=5
} |
These are my loaded modules:
| Code: | Module Size Used by
iwlmvm 97018 0
acpi_call 4424 0
tp_smapi 16678 0
thinkpad_ec 4005 1 tp_smapi
btusb 16933 0
bluetooth 219597 2 btusb
iwldvm 131694 0
mac80211 444760 2 iwldvm,iwlmvm
kvm 408601 0
crc32c_intel 14215 0
microcode 7407 0
pcspkr 2006 0
iwlwifi 85106 2 iwldvm,iwlmvm
cfg80211 462180 4 iwlwifi,mac80211,iwldvm,iwlmvm
thinkpad_acpi 70282 0
e1000e 196865 0
rfkill 18530 4 cfg80211,thinkpad_acpi,bluetooth
shpchp 26776 0 |
I have ensured that power management is off for wlp3s0 and Network Manager and wicd do not run as mentioned elsewhere.
What else should I check?

hi,
my X230 with Centrino Advanced-N 6205 AGN wireless card, (rev 34)
try:
/etc/conf.d/net:
| Code: |
...
wpa_supplicant_wlp3s0="-Dwext"
...

Hello Terrere, thanks for your help,

I tried that but cfg80211 still spammed my logs. In fact the spam continues even when /etc/init.d/net.wlp3s0 is stopped.
So now I've built a new kernel with | Code: | | CONFIG_CFG80211_REG_DEBUG=y |
and syslog now endlessly reports: | Code: | kernel: cfg80211: Calling CRDA for country: 97
kernel: cfg80211: Timeout while waiting for CRDA to reply, restoring regulatory settings
kernel: cfg80211: Keeping preference on module parameter ieee80211_regdom: UK
kernel: cfg80211: Kicking the queue
kernel: cfg80211: Calling CRDA to update world regulatory domain
kernel: cfg80211: Ignoring regulatory request Set by core since the driver uses its own custom regulatory domain
kernel: cfg80211: World regulatory domain updated:
kernel: cfg80211: (start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp)
kernel: cfg80211: (2402000 KHz - 2472000 KHz @ 40000 KHz), (300 mBi, 2000 mBm)
kernel: cfg80211: (2457000 KHz - 2482000 KHz @ 40000 KHz), (300 mBi, 2000 mBm)
kernel: cfg80211: (2474000 KHz - 2494000 KHz @ 20000 KHz), (300 mBi, 2000 mBm)
kernel: cfg80211: (5170000 KHz - 5250000 KHz @ 40000 KHz), (300 mBi, 2000 mBm)
kernel: cfg80211: (5735000 KHz - 5835000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) |
The line Ignoring regulatory request Set by core since the driver uses its own custom regulatory domain looks important, but I'm not sure I understand it yet. |

Oh dear! I think its all a matter of country codes. It seems that when I change /etc/modprobe.d/cfg80211.conf from | Code: | | options cfg80211 ieee80211_regdom=UK |
to | Code: | | options cfg80211 ieee80211_regdom=GB |
all my troubles are over! The Irish might have something to say about that! |
