I'm getting a "No handler for interrupt 259" message while this B160 is booting. This is occurs because no one has registered an interrupt handler to use EIRR bit 3. IRQ region 1 (IRQ's 256-511) is for the CPU. Enableding "DEBUG_IRQ" in arch/parisc/kernel/irq.c produces the "1+3" seen in the output. Shortly after the spurious interrupt, Dino gets assigned this bit. But I think that's just a coincidence since Dino registers haven't been initialized by the dino driver yet. The value in Dino's IAR0 register is 0xfffffff8 - not even a valid CPU address. So who *is* generating interrupt on EIRR bit 3? And do they interfer with Dino operation later by generating additional spurious interrupts? Please ignore the "Code 8" at the end of the console output for now. That's a different problem... thanks, grant Main Menu: Enter command > bo lan Interact with IPL (Y, N, Q)?> n Booting...
