But that changes if any of - GENERIC_LOCKBREAK - DEBUG_SPINLOCK - DEBUG_LOCK_ALLOC (and if so, LOCK_STAT) is set, and then you might actually get to 72. However, the Code: line for one of the oopses shows that in that particular case, it was at offset 0x18 (ie the normal 24), so at least one of the oopses had no such thing going on.
