Hi,
 
Can xen developers kindly post relevant solution to this problem. I have seen many times on xen list-  not a simple answer. It has come to the point of frustration. I can provide any information needed.
 
Regards,
Vineet

Switching to new root
switchroot: mount failed: 22

Then system reboot.In grub.conf,I have change d the root=LABEL=/ to the actual device

I have tried giving different options to creation of mkinitrd command but it doesnot work. I have tried "builtin" and "with" options and it doesnot worl. In addition, I have tried to make hyperthreading disabled,it doesnot work for me.
I have seen many such messages but no concrete solution to this problem. Please help.
