--- Comment #4 from Michael Reim <krail...@elderlinux.org> ---
(In reply to Ed Maste from comment #1)
Thanks for the quick fix! It solved that problem and lead to the machine boot
further. With r357045 I'm getting a new panic, though (this time obviously from
the VM system):
Hit [Enter] to boot immediately, or any other key for command prompt.
Booting [/boot/kernel/kernel]...
jumping to kernel entry at 0xc00b8020.
