Description Ra P. 2008-03-12 16:51:17 UTC

Since upgrading kernel-2.6.23.15-137.fc8 to kernel-2.6.24.3-12.fc8 the parameter
ieee80211_regdom=64 for module mac80211 isn't available anymore. This is
necessary to use wireless channels which else aren't available.

While using the new kernel the following command fails:
modprobe mac80211 ieee80211_regdom=64

Modinfo also doesn't show the missing parameter anymore:
[root@localhost ~]# modinfo

mac80211 to use (charp)

The old module has this parameter:

Comment 1 John W. Linville 2008-03-13 15:02:26 UTC

Ah, sorry about that.  The mechanism for changing that has changed upstream.  
You will need to get rid of this line in /etc/modprobe.conf:

   options mac80211 ieee80211_regdom=64

And add this instead:

   options cfg80211 ieee80211_regdom="JP"

Unfortunately I don't see any reasonable way to hack around this to preserve 
the old mac80211 module option for F8.  I'm sorry.
