Which kernel is the host running and which kernel is the guest
running? And which kernel has the vsyscall=emulate parameter? If
vsyscall=emulate is a problem on a pre-3.3 kernel, can you try
something containing commit 4fc3490114bb159bd4fff1b3c96f4320fe6fb08f?
(UML, for example, is known to have serious issues without that fix.)

Otherwise, can you tell me what hypervisor you're using and what init
version (i.e. the rpm) so I can try to reproduce it? A pointer to an
actual image would work, too. A copy of the oops would also be nice.
