>Description:
      When I do a shutdown -r or reboot, my dual-P3 box hangs on this:

Shutting down ACPI
rebooting...
cpu_reset called on cpu#1
cpu_reset: Stopping other CPUs
cpu_reset: Restarting BSP
cpu_reset_proxy: Stopped CPU 1


Sometimes it will sit there indefinitely.  Other times it may eventually reboot... but this takes quite some time (10+ minutes)
>How-To-Repeat:
      This happens _every_ time I try to reboot.
>Fix:
      None that I am aware.  This does not affect my single-cpu boxes.  If it helps, I am running a Tyan Thunder100 board, with a 440BX chipset.
