Cannot boot jessie kernel on qemu armhf VM

["Christoph Pleger" <Christoph.Pleger@cs.tu-dortmund.de>]

Hello,

I created a qemu armhf virtual machine, with machine type vexpress-a9 and
CPU cortex-a9. I first attempted to install the VM by using the jessie
debian-installer, but the VM did not boot. As is was not sure if I had the
correct files vmlinuz and initrd for jessie, I tried wheezy instead, and
that worked. After wheezy installation was completed, I upgraded to
jessie, installed vmlinuz-3.16.0-4-armmp kernel, halted the VM, copied
/boot/vmlinuz-3.16.0-4-armmp and /boot/initrd.img-3.16.0-4-armmp from the
VM to the real machine and, in my qemu GUI aqemu, changed the entries for
direct kernel boot accordingly. But again, the VM does not boot with
jessie kernel - the qemu window opens, but then, nothing happens any more.
With the wheezy kernel, the VM still boots fine.

Any suggesting how to make the jessie kernel work on my VM?

Regards
