Description Juha Heljoranta 2008-05-02 16:20:40 EDT
Description of problem:
Tried to activate wlan0:0 resulted system lockup. The command was ifup wlan0:0.
This hasn't happened before. Probably related to kernel or otherwise
hard to reproduce.

Version-Release number of selected component (if applicable):

How reproducible:
Create alias with static ip in addition to dynamically configured wlan0 and
activate manually (ifup wlan0:0) after wlan0 is up.

Steps to Reproduce:
None successful so far. Tried few times.

Actual results:
System lockup.

Expected results:
Working alias for wlan0.

Has this worked in the past?  I imagine that this might confuse the mac80211 
component, not sure...
