Cisco VPN client + Wireless + Multiple CPUs (SMP) = CPU freeze.

There is a problem with Cisco VPN client when used on a wireless network with multiple CPUs. I was able to verify this by connecting my laptop to a wired ethernet line without any problems. When I went wireless, my laptop froze.

I'm not sure what you can do in Windows, but in linux, I disabled one of my processors prior to establishing my VPN connection and everything works fine. (ex. # echo 0 > /sys/devices/system/cpu/cpu1/online )

After I disconnect, I re-enable the CPU. ( ex. # echo 1 > /sys/devices/system/cpu/cpu1/online )
