[Xen-devel] kernel panic doing mem-set

[Patrick O'Rourke <porourke@xxxxxxxxxxx>]

x86_32, no PAE, I see the following when trying to set dom0's memory 
down to 512MB (note: there is a total of 12GB of RAM).  Seems we're 
hitting this statement:
BUG_ON(HYPERVISOR_memory_op(
        XENMEM_decrease_reservation, &reservation) != debt);
