Hi,

This seems to be a common problem these days, see:

I didn't have a chance to properly work out what is going on there,
but the suggested patch did not allow me to select an ac channel,
returning the same error seen in the attachment.

Did you specify an appropriate module param? The patch alone doesn't
change anything.

Do you use CRDA on your system or do you have db.txt compiled in your
kernel? Perhaps your system level regulatory is still at world roaming
so all 5GHz channels are locked out.

If you use latest `iw` tool the `iw reg get` will show you both system
level and device level regulatory.

Please try to avoid sending badly formatted messages :)

From the logs you provided it looks like you're stuck at world
regulatory (00). This means that you have an empty db.txt file (if you
compiled kernel with built-in regulatory) or your system doesn't have
CRDA binary and/or regulatory database for it to use. You might be
missing udev/hotplug to handle the CRDA request as well I think.

Did you do that in the kernel 3.12 source tree or backports? Are you
sure you have db.txt compiled in? The hostapd logs suggest otherwise.
It looks like regulatory change times out suggesting that either
there's a deadlock in cfg80211 or it expects CRDA binary to handle the
request (but there's none to do so).

Can you post entire kernel log (dmesg), please?

See? It stays at country 00 with entire 5GHz still locked out.

You clearly have not compiled cfg80211 with db.txt built-in. It's
compiled to use CRDA which your system is missing (hence the timeout
message).

You either need to:
 - actually compile backports with db.txt built-in
 - fix CRDA (install the binary, database and make sure udev/hotplug is set up)

Hi Michal,

CPTCFG_CFG80211_INTERNAL_REGDB was not enabled in backports though we had added db.txt.
it started working. thanks...
