It seems that my problem was related to turning off sys_auxpll, which
is the clock source for the PCI bus. If I just comment out the write
to sys_auxpll in au1000_restart() then the reboot seems to work just
fine. I'm not sure why disabling the PCI clock would cause yamon to
take a TLB fault... I guess I need to hook up the analyzer and see
what happens to the PCI devices when the PCI clock goes away.
Thanks for the suggestions,
Clem
