Thomas,
I (belatedly) took a look at fixing ia64 ... but I've run into a small snag.
The __do_IRQ() routine makes a call to:
desc->chip->end(irq);
while neither of the "handle_level_irq()" nor "handle_edge_irq()"
functions do this.
On ia64 iosapic_end_level_irq() call iosapic_eoi() for me. Without it
my system hangs during boot (with some driver timeout complaining
about dropped interrupts).
Is the omission of desc->chip->end(irq); deliberate? In which case
I need to find another place to call iosapic_eoi(). Or is it accidental?
Thanks
-Tony
