The long delay happens during device discovery.
You could enable EARLY_BOOTUP_DEBUG in arch/parisc/kernel/pdc_cons.c
and add some printk's to the loop in system_map_inventory().
Only two pieces of code really get executed during that time.
One is the PDC calls - verify your firmware is the latest and if it
isn't, please update. The other might be GSC buswalk code. I thought
the bus's under U2 are walked to detect devices not listed by PDC.
But I don't know exactly when that occurs in the boot sequence.
