Will do as you instruct. It'll probably be the weekend before I can get the shadow systems running for our experiments. I was running 2.6.22-rc3 at one point and saw the problem, so we'll probably get something interesting from the sysrq. Thanks for the precise insturctions; that's about the right level of detail for my inexperience doing this sort of thing. :) Cheers, -mcq ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
