Looks like it may be the same problem I have encountered (see thread 
'dom0 panic on domu dettach'). If I shutdown the domu, the vnd slot was 
still occupied and forcing an unmount would panic the dom0. Rebooting 
the domu would cause the panic straight off.

I don't use hvm so I could be way off.

I was going to try and obtain more information but have just updated to 
the latest kernel as of yesterday. I'll report back in a minutes.
