This is a known issue that's being heavily investigated, but is proving 
very elusive. See http://lkml.org/lkml/2009/10/22/128 for an overview.

Can you easily reproduce the problem, or does it happen at random moments? 
If you can reproduce it, it would be great if you could test the patches 
mentioned in that mail.

Cheers,
FJP
