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,
