Hi Ankita,

It's strange that you have been able to boot itto same kernel[I assume] in VM
but not on your machine. Probably something went wrong while installing
the modules on your machine. Which rc version did you try to install?

I'm free for few hours right now. If you can come on IRC, we can try to
debug the problem. I'm 'vaishali' on both freenode and OFTC. Just ping
me there.
