Hello! I have a question: what happens on a XIO invalid access? I am looking at the MGras MAIN_WIDGET space and sometimes the Octane just locks up. I have captured all exceptions (I pass interrupts to the original PROM handler) and an access to MAIN_WIDGET_BASE+00020104 causes a hang. The reset button works, which is nothing special. But the power button works, too, and that's something I don't really understand, as it is an interrupt, too. Do you know something more about XIO exception handling? Thank you in advance, Stanislaw Skowronek --<=>-- Paranoid: one who is truly in touch with reality.
