Hi!
I’m usingen Debian/Testing with xen-hypervisor-4.0-amd64. Kernel for Dom0
is 2.6.34 with xen-patches-2.6.34-1.tar.bz2, kernel for DomU is the
standard 2.6.34.
With all udev version since 153-2, I can’t start my DomU. The following
oops is happening:

Going back to 153-2 resolves the problem. Is this a bug in udev or in

Shade and sweet water!
