Hello.
I don't know if this is the right place to post a bug. I use Gentoo with
a 2.6.15-gentoo-r1 kernel on a SMP P4 laptop (my wlan card is an Airvast
168b).
I also use a vanilla linux-wlan-ng 0.2.3 on this kernel.
Just after I execute
wlanctl-ng $DEVICE lnxreq_autojoin ssid="$SSID" authtype="opensystem"
the kernel hangs, giving the following error message:

======================
I have been able to avoid the error by putting a 2sec/pause between this
command and the following (dhcpcd $DEVICE). But it doesn't always work.
Sometimes I have to wait until the computer completely boots up, then
executing the commands by hand. And I always have to reset the card when
I power on the computer again, even if everything worked well the last
time I used it.
This error didn't happen to me with the 0.2.2 version of linux-wlan-ng
that came with Gentoo, but I have had to upgrade because the old version
does not compile with the new kernel. I have had similar problems with
older versions of linux-wlan-ng, so I think it might be a regression.
Thank you!
