	Apple Macintosh Quadra 700  (68040)

Architecture: m68k
Machine: mac68k

>Description:

	The machine runs an X server on the console. After the xdm
	login, the xinitrc script attempts so start a gkrellm on
	another machine via rsh and dies.


>How-To-Repeat:

	Boot Quadra 700 with new kernel, freshly built from 2003-01-12
	sources.  Start a remote gkrellm via rsh.

	The final 'sync' from ddb either locks up or panics the
	machine again.
