"oanix"? "tarp"?
are these consistent typos or parity bozons for "panic" and "trap"?

There appear to be three independant problems:

a)    your original page fault failure; no clue on this. New ktrace code
      from Bill Sommerfeld?

b)    Recursive traceback printing. This is my fault, and I'll scratch
      my head and decide how best to deal with it. Perhaps we should
      not try to print tracebacks recursively.

c)    System freezes after 5 traps. No clue here.

I presume this is reproducable.
