Hello Thomas,

Wow.. that's a key find!  Nice work!  Now that you narrowed this down to 
a threading issue with a easy way to reproduce it, I hope you'll get 
some traction here from the local kernel experts.  If you don't see much 
movement, I imagine taking this up to the main kernel list would be 
warranted.
