 I'm trying to boot my domU kernel and I get the error as shown below: I
 made some changes to the kernel and added my module for a particular
 driver only. Any idea where this error is creeping in from? I also
added some changes to standard structures(task structure). If there is
any offset calculation etc. that Xen does then it may be one of the
reasons for failure. Kindly help.
