Can you find out *why* the later page faults occur? Printing the ISR
should help. The page fault handler does not (yet) setup si_isr in
the siginfo, but you could just hack
arch/ia64/mm/fault.c:ia64_do_page_fault() to print the ISR when you
detect the problematic case.
If you have a (small) test program that replicates the problem, I'd be
happy to look into it early next week.
