#5956: PPC boot fails on double lock of mutex

Comment(by bonefish):
Mutexes don't have IDs, they are just structures in memory. And 0x1c
suggests a NULL pointer. Apparently it's so early in the boot process that
this address is still accessible, otherwise it would be an unhandled page
fault. I'd recommend to get at least the stack traces going. On a panic a
stack trace is printed automatically, but that requires a working
arch_debug_call_with_fault_handler() implementation ([http://dev.haiku-
os.org/browser/haiku/trunk/src/system/kernel/arch/ppc/arch_debug.cpp#L311]).
