Try compiling the kernel with DDB enabeled. Try to mount the CD while on the first virtual console. When the machine hangs use ctrl-alt-esc to break into the debugger and use "trace" to find out what the kernel is up to. It may be worth using "continue" to let the kernel go on and then break into the debugger again to see if where the kernel running is changing or static. David.
