I got something similar when the VM was not quite right on Xen-3. When
starting init, the kernel forks() from proc0 and this new process will
do all the work of searching the binary and load it. Getting a EFAULT here
means that this process got a segfault somewhere, and as it's not
really in kenrnel context it doesn't panic.
It could, for example, gets a fault while trying to read the filesystem.
