Since the RiscPC is not an ISA-based machine, the conventional PC interrupt
numbers do not apply. IRQ7 is in fact the same as IRQ7 under RISC OS, which
is internally always asserted in the IOMD.
I'm a little surprised that you're seeing any IRQ hanging the machine,
especially as the IRQ lock detection is designed to get you out of those
problems.
As far as the lack of IRQ, I'll look into it when I next boot a 2.4 kernel
on the RiscPC.
BTW, this should really be on the linux-arm-kernel mailing list.
