Re: [Xen-ia64-devel] Bug in domain.c:construct_dom0()
Haavard,
I just worked around this in my tree yesterday (are you looking at
getting event channels working too?)... the problem is that shared_info
goes over a page boundary and thereby corrupts the domain structure,
if you reduce MAX_VIRT_CPUS it will fix the problem.
