Setting the EU or DE regulatory domain (cfg80211 ieee80211_regdom=EU)
seems to be working, but afterwards inserting the rtl8187 driver causes crash:

I have yesterday's compat-wireless (v2.6.29-rc8-18669-g77f1f84), and
setting EU seems to make it stop responding to setting anything else
(no more CRDA dmesg messages after the EU entry) - the driver is still
operational though...
will give today's wireless-testing a try :-).

Ouch. I suck. And the problem is blindingly obvious:
+ if (sdata->vif.type != NL80211_IFTYPE_ADHOC)
+ return ieee80211_ibss_rx_mgmt(sdata, rx->skb, rx->status);
needs to be == of course!

Please try with today's wireless-testing a set of fixes went in to
address a bug with "EU". Mind you, "EU" is an invalid ISO3166-alpha2
so you may want to consider start using your own valid country alpha2
code. If you use "EU" now you'll world roam.

The problem is more general than rtl8187. The system freezes when I try to
connect with rrtl8187 or b43. Using bisection, the bad commit is as follows:

I have not yet tried to see which hunk or hunks cause the proble, but backing
oout that patch allows the system to work correctly.

Its complete crap, in fact stop using the module parameter. "EU" is
part of the 3 static regulatory domains left from the old regulatory
implementation. It should have been removed eons ago but old habits
are hard to kill. Fortunately distributions are now shipping and with
OLD_REG disabled on 2.6.28 (both FC11 and Ubuntu Jaunty). The "EU"
option and even the ieee80211_regdom module parameter are simply not
an option in 2.6.28 and 2.6.29 if OLD_REG is disabled, we have a
suitable replacement -- a userspace call.
Unfortunately I just added the module parameter when OLD_REG is
disabled to try to remove OLD_REG completely but that didn't seem to
work yet.

Heh, well its easier than that you get a ISO / IEC 3166 alpha2 for
each country. So you just pick your country. "EU" is an ancient
regulatory concoction, it should be ignored and forgotten.

So, not all of my patches were applied... Specifically the one that
removed OLD_REG was not applied. This is why you are getting "US"
still as your default. You probably have OLD_REG enabled in your
kernel.

So.. this still happens because within OLD_REG "DE" is not a valid
static regulatory domain, so first you get by default the "US" static
regulatory domain. That is -- if you want to use OLD_REG and get a
static regulatory domain applied by default first you only have 3
options:
"US"
"EU"
"JP"
Now this is pure garbage and which is why people should stop using
OLD_REG and forget about it.
> [ =C2=A0687.552501] cfg80211: Calling CRDA for country: DE
Strange well I just tested with OLD_REG and I get the same "US" crap
as above but then immediately after that I got "DE" as follows:
[15895.175144] cfg80211: Regulatory domain changed to country: DE
[15895.175189] (start_freq - end_freq @ bandwidth),
(max_antenna_gain, max_eirp)
[15895.175241] (2400000 KHz - 2483500 KHz @ 40000 KHz), (N/A, 2000 mBm=
)
[15895.175274] (5150000 KHz - 5255000 KHz @ 40000 KHz), (N/A, 2301 mBm=
)
[15895.175312] (5470000 KHz - 5650000 KHz @ 40000 KHz), (N/A, 3000 mBm=
)
You probably don't have the wireless-regdb and crda installed. We have
offloaded all this regulatory information to userspace, you know get a
decent world roaming regulatory domain by default instead of assuming
everyone lives the United States. Then you can set the regulatory
domain.
http://wireless.kernel.org/download/wireless-regdb/
sudo make install
http://wireless.kernel.org/download/crda/
make
sudo make install
Then you should get your "DE".

I don't see any panics, everything is as expected --except my removal
of OLD_REG patch was not applied.

Yes, fgrep OLD_REG /boot/config-2.6.29-rc8-wl

Hmm, there is a lot bogus information or howtos on the web.
Somebody probably should incorporate exactly this information
on the web-page http://linuxwireless.org/en/developers/Regulatory
E.g. I didn't know what "static regulatory domain" really means.

Sure, I tried "DE" with the same result as well.
Fortunately, wireless-testing doesn't crash during the rtl8187 driver load
anymore, but changing the regulatory domain seems to be no-op (see below).
Furthermore the current wireless-testing breaks the rtl8187 driver completely.
If I try to connect to an AP (with or without changing the domain),
it hard-freezes the kernel without any log entry.

I wonder why is there than the EU (confusing) code at all?
Actually I would expect a "smallest common intersection" of the 27 European
Union member states.
