By definition, if the system is truly hung, then there's way to give control to the part of the kernel that takes crash dumps. If this system is only pseudo-hung, you can escape to the debugger and tell it to `call boot(0x104)' and it will attempt to take a crash dump. Often times, the problems that cause a hang are the same ones that may cause a crash dump to fail. -GAWollman -- Garrett A.
