It still panics, but more predictably: Great! I'm hunting this kind of panic for long time, but it never was so stable. Can you send me "show pmap addr" output from kdb after panic - pmap address is in panic message. However, understand that it's two different things. Your problem is not the panic. It's caused by primary problem which is caused by something we need to figure out.
