Problem Description:
I can't boot up with a plugged WLAN - Usb Device. There are no important errormessages while booting up. I tried to connect while Kanotix were running and dmesg gave the following output:

Wireless core crashed in netdev_notify().

It might help if you could identify more precisely which kernel version

I assume it also crashes when the nvidia driver has never been loaded?

Kernel 2.6.27-rc3-git2 was used. And yes, you assume right. :-)

Comment 3 uwe 2008-08-20 04:09:13 UTC
New edit:

I tried kernel 2.6.27-rc3-git6 and it still doesn´t work.
If it helps, here the output of lspci -nn:

Comment 4 John W. Linville 2008-08-20 08:50:01 UTC
Please attach the output of this command:

   objdump -d /lib/modules/`uname -r`/kernel/net/wireless/cfg80211.ko

The backtrace leaves cfg80211_netdev_notifier_call very early...it could be getting passed something bad as input.

What is mcount_call?  Seems to be related to ftrace...please also attach your .config file.

As requestet the output of objdump
Comment 6 uwe 2008-08-21 11:34:13 UTC
Created attachment 17358 [details]
as requestet the .config file
Comment 7 John W. Linville 2008-08-22 10:34:47 UTC
Can you disable CONFIG_FTRACE ("Kernel Function Tracer") and rebuild?  Can you recreate the problem with ftrace disabled?
Comment 8 uwe 2008-08-31 13:06:54 UTC
I'm sry that it took some time with my answer. I'm not so firm in building a kernel. I tried it as you requested with a disabled CONFIG_FTRACE and there was no change. But maybe that information will help. 
I tried ubuntu 8.10 beta and with the livecd i can boot up and have a connection with this USB-WLAN-device.
Comment 9 John W. Linville 2008-09-12 15:33:03 UTC
AFAICT, mcount_call (which is in the trace you provided) doesn't exist if CONFIG_FTRACE isn't set...are you sure you are running a build with CONFIG_FTRACE turned-off?  If so, then the trace should have at least that difference (i.e. no mcount_call)?
Comment 10 John W. Linville 2008-09-16 13:38:23 UTC
I would like you to do two things:

Attach /etc/udev/rules.d/70-persistent-net.rules to this bug; and, delete /etc/udev/rules.d/70-persistent-net.rules and reboot.

Does the problem persist after the 2nd part above?

Comment 12 Johannes Berg 2008-10-08 01:27:37 UTC
I've found a small bug that might have been causing this, see http://thread.gmane.org/gmane.linux.kernel.wireless.general/21902
