+On AMD 29000 family processors, registers are saved in a separate ``register
+stack''.  There is no way for GDB to determine the extent of this stack.
+Normally, GDB just assumes that the stack is ``large enough''.
+This may result in GDB referencing memory locations that don't
+exist, you can specify the ending address of the register stack with the
+@code{set rstack_high_address} command.  The argument should be an address,
+which you will probably want to precede with 0x and specify in hexadecimal.
