Re: performance monitor exceptions

Bingo ! That seems to be the one:

  #5:
  Description: Consecutive Performance Monitor, Decrementer,
  or Thermal Management Interrupts may become non-recoverable.

  Work-Around: Avoid enabling any combination of
  Performance Monitor, Decrementer, or Thermal Management
  Interrupts at the same time.

Thats rather ugly :( BTW I have run kernel profiling off the performance
monitor exception on ppc64 which has been very useful (it allowed us
to profile inside interrupt disabled regions)
