I attached a .kev file the IDE chokes on, either version 4.7.0 or 4.6.0.  The file comes from a QNX6.4.1 machine.

I'm guessing it's an hardware problem of some sort because on an other machine, which has the same config, it works ok. 
 At anyrate you could use to file to make the system profiler more robust.

Not sure if it's related or not but pidin info report 2 cores to be of different speed then 2 other core ( it's a quad 
core machine)!!!  I'll be looking into that.
