Happens for me - full reproducible as follows.
Start Ubuntu 10.10 on battery, or on mains then unplug mains.
Attempt to log on to wireless network.
Machine freezes as the wlan card connects.
I am using the temporary work around from http://www.uluga.ubuntuforums.org/showthread.php?p=10327529 : "sudo iwconfig wlan0 power off" before trying to connect to wlan. That thread too is pointing to problems with pm-utils 1.4.
