Hi Martyn;

Yes, thanks.  Right now my only suggestion would be to back up to the 
2.6.12 kernel.  I'm seeing some strange behavior from the 2.6.13 
kernel.  The traces I've collected on my host and the trace Clayton Keller 
sent me both show this problem.  I'm trying to figure out how to report 
this to the Linxu developers.
