   I remember seeing this kind of error when playing with using
PAL_HALT_LIGHT in the cpu_idle loop.  Newer PAL solved the
problem.  If you have CONFIG_IA64_PAL_IDLE turned on in your
config file, you either need to upgrade to new firmware (not
sure what rev to recommend on a tiger box) or disable the config
option and rebuild a kernel.  Try for PAL 7.40 or better.
Thanks,

	Alex
