Hi Yi,

don't bother trying to track down the exact commit. This bug has been  
introduced sometime between 2.6.26 and 2.6.27 and was originally a BUG  
that crashed your machine. My last working kernel without this problem  
was the Ubuntu 8.04 kernel.

So starting with 2.6.28-rc1, Johannes turned the BUG into a WARN_ON  
and now we do actually see the issue and the code in question. Check  
kerneloops.org for reference since I did post all of my warnings there.

Regards

Marcel
