How can I avoid kernel panics under Tiger, OS 10.4?
The Contivity VPN client (version 3.3) may cause a kernel panic when you want to stop it. As it is stops when you shut down or restart the computer, it means that sometimes your computer will go into a kernel panic instead of restarting or powering off. This was almost systematic before 10.4.2. One solution is to stop the VPN client when unused. If you are on 10.4, you cannot do this under the default installation. The workaround is to remove the command that unloads the Contivity kernel extension.
