Here's what that machine check stack frame means:
803AF1E8 0000000C 12 bytes of parameters
803AF1EC 00000082 Machine check code = Write bus
error, virtual address
803AF1F0 7FF38058 Virtual address

It seems that you are getting hard memory write faults on the stack.
Maybe something is hanging up the Q-bus, or you have failing memory.
If you have diagnostics, running a memory test for a while may get you
somewhere. Otherwise, I'd look into trying to pinpoint the problem by
removing memory modules and see if the system becomes more stable
(assuming you have multiple memory cards, of course).
