CRDA infinite messages after upgrade to 11.10

[Xylian]

Hi,
yesterday I've upgraded my Ubuntu 11.04 installation to 11.10 and I'm having troubles with CRDA, since it's flooding the syslog with continuous messages.. I've set the following:


# cat /etc/modprobe.d/cfg80211.conf
options cfg80211 ieee80211_regdom="EU"

But something wrong happens at boot:


cfg80211: Calling CRDA for country: EU
cfg80211: Timeout while waiting for CRDA to reply, restoring regulatory settings
cfg80211: Restoring regulatory settings including user preference
cfg80211: Keeping preference on module parameter ieee80211_regdom: EU
cfg80211: Calling CRDA for country: US
cfg80211: Updating information on frequency 2412 MHz for a 20 MHz width channel with regulatory rule:
cfg80211: 2402000 KHz - 2472000 KHz @ KHz), (300 mBi, 2700 mBm)
[...]

And then udev keeps sending regulatory domain settings for country 97:


cfg80211: Calling CRDA for country: 97
cfg80211: Timeout while waiting for CRDA to reply, restoring regulatory settings
cfg80211: Keeping preference on module parameter ieee80211_regdom: EU
cfg80211: Adding request for country EU back into the queue
cfg80211: Adding request for country EU back into the queue
cfg80211: Adding request for country EU back into the queue
cfg80211: Adding request for country EU back into the queue
cfg80211: Adding request for country EU back into the queue
cfg80211: Adding request for country EU back into the queue
cfg80211: Kicking the queue
cfg80211: Calling CRDA to update world regulatory domain
[...]


Monitoring UDEV messages to the kernel, I see continuous messages like the following one:


# udevadm monitor --environment kernel
monitor will print the received events for:
UDEV - the event which udev sends out after rule processing
KERNEL - the kernel uevent

KERNEL[1950.592767] change /devices/platform/regulatory.0 (platform)
UDEV_LOG=3
ACTION=change
DEVPATH=/devices/platform/regulatory.0
SUBSYSTEM=platform
MODALIAS=platform:regulatory
COUNTRY=00
SEQNUM=2829


Any idea about how to solve the problem? I've seen there was a bug related to kernel 3 here: https://bugzilla.novell.com/show_bug.cgi?id=700159#c0

I have same problem here.
My wireless is on channel 13 and laptop does not connect after reboot. I tried to run command:
sudo COUNTRY=FI crda
But it gives error:
Failed to set regulatory domain: -7

So then I had to add /etc/modprobe.d/wireless file with content;
options cfg80211 ieee80211_regdom=EU

After reboot my laptop still does not get into channel 13
sudo iwlist f

dmesg tells more detailed error:
cfg80211: Calling CRDA for country: 97
cfg80211: Timeout while waiting for CRDA to reply, restoring regulatory settings

So now I can get network working only by removing all wireless kernel modules and loading them back again. So then(?) this ieee80211_regdom=EU is registered and I can get all channels.
dmesg:
Keeping preference on module parameter ieee80211_regdom: EU

So there are bugs somewhere which is not reported widely yet. Or people are just using channels 1-11 only.
I read somewhere document that Ubuntu clock settings are used to get location and regulatory setting. So then running this command manually. But as it does not work neither I had to push location via kernel module option.

Thinking to leave Ubuntu and changing somewhere else (not Ubuntu based). Maybe Fedora is my next option...

Considering this thread is the only Google result on the exact error message (that is not a code patch that contains the message string), and nobody cares in this thread, I have created an Ubuntu bug here: https://bugs.launchpad.net/ubuntu/+bug/899335 Hope it gets more attention over there.

Hi,

are there some news about that? Or would it be fixed in 12.04?

I have a similar problem here, I also can't use channel 12 & 13 with the awus036nhr (rtl8192cu module).
In syslog it says things like:

"Disabling freq 2467 as custom regd has no rule that fits a 20 mhz wide channel"

regardless of which iw reg set xx I do..

Very annoying.. especially because it works under Windows on the same hardware..

Has someone tried to recompile the Kernel without using CRDA?

with CONFIG_CFG80211_INTERNAL_REGDB ?
