OK, that's good.

This might be an (IRQ) problem, see below.

Ditto.

That's strange, probably even misleading. The actual reason for the hang
is likely in some other place. My guess is that the IRQs are messed up.

Can you try to boot the kernel with the 'irqpoll' option and see if that
helps? Also, are you sure the irq_table.c in the patch is correct?
I think it was generated with getpir on your 4000s? Anyway, sometimes
even the tables of the proprietary BIOS are crap, so...
