Occasionally stopping amd freezes my system. It's a rare occurrence, and I haven't found a reliable way to reproduce it. It's also a real freeze, so there's no way to get into the debugger or grab a core dump. I only can perform the 4 seconds hard shutdown to revive the system. I run amd through sysutils/automounter, which is a scripting solution that generates an amd.map file
