The problem may be worse than that. I see that you have a per-cpu
"call_single_queue" on which you do some list operations. On ia64
the per-cpu variables live at the same virtual address on each processor
with a per-cpu TLB mapping directing them to a different physical
address on each. This makes Linux lists very confused.
