>How-To-Repeat:
Boot the netbsd-INSTALL32_IP2x kernel via bootp/tftp.
>Fix:
Last line before panic was:

panel0 at hpc0 offset 0x59800

I'm suspect this might be caused by the new driver for the Indy front panel 
buttons (the Challenge S has no connection to the front panel buttons):

sys/arch/sgimips/hpc/panel.c                    1.1

        Add a driver for the Indy's front panel buttons.
        - power button presses are reported to sysmon
        - volume control buttons are reported to PMF
