Reproducible: Always Steps to Reproduce: 1. Install openSUSE 12.2M2 or M3 on a system with ipw2200-WLAN 2. start the YaST network module or anything that probes the network (with ethtool) 3. Actual Results: kernel gets stuck on cpu, WLAN does not work Expected Results: WLAN should work. Eventually I got the network running by: 1) blacklisting ipw2200 by adding it to /etc/modprobe.d/50-blacklist.conf 2) starting it later by adding "/sbin/modprobe ipw2200" to /etc/init.d/boot.local 3) switch network control from NetworkManager to if-up The switch from NetworkManager to if-up was necessary, because NetworkManager offered only WEP+LEAP as security levels, not WPA+WPA2 after the first two steps. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I guess this is caused by a change in udev. See this post by Kay Sievers: http://www.spinics.net/lists/linux-wireless/msg83422.html And the udev version 173 from openSUSE 12.1 seems to be old enough, to work.
It might be related. To be sure, would it be possible to check when the firmware is loaded ? Observe messages "tail -f /var/log/messages" and: - bring down the interface "ifconfig wlan0 down" - unload the driver "rmmod ipw2200" - load the driver "modprobe ipw2200" - take a look on the interfaces "ficonfig -a" - bring the interface up "ifconfig wlan0 up" Can you see in the messages when the firmware was loaded ? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Update: test with openSUSE 12.2 RC2
WLAN works now with this driver and since RC2 even the KDE network management app is able to deal with this hardware and driver. The only two (minor) things, that are not good:
- the network related hardware detection during installation is still very slow (probably timeouts) - the tray icon does not show the signal strength
The signal strength is fixed in bnc#755541. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
