By any chance, does your board has a another timer (i.e other than the
generic timer)?
I would also track down to see who is adding this timer.
But after apply the above kernel patch, Dom0 Linux can handle shell input.
Just have another question, How can Dom0 handle DMA for arm.
When Xen is allocating the RAM bank for DOM0 we use a direct mapping
(i.e the Physical Address = Intermediate Address for the RAM). So DOM0
can perform DMA as on baremetal.
