Subject: 2.6.6-rc3 ia64 smp_call_function() called with interrupts disabled
2.6.6-rc3, modprobe sg calls vfree() with interrupts disabled. On
ia64, vfree calls smp_flush_tlb_all() which calls smp_call_function().
Calling smp_call_function() with interrupts disabled can deadlock.
Badness in smp_call_function at arch/ia64/kernel/smp.c:312
Call Trace:
