Mailing List Archive: xen 4.1.1 with current linus tree as dom0 [ 0.000000] BUG: unable to handle kernel NULL pointer dereference at (null) [ 0.000000] IP: [] xen_set

Hi Jeremy/Konrad,

I'm still trying to get the current linus tree (commit ed8f37370d83e695c0a4fa5d5fc7a83ecb947526) to boot as a dom0 kernel under a xen 4.1.1 hypervisor.
But still can't boot (after compiling with tracers disabled).

.config attached
