I just got (probably) the same panic while testing tuntap networking
(more about that in a bit :) with a linux/amd64 guest running with
svm and npt enabled - it was scp'ing a file out of the guest at about
16 MBytes/sec when the panic happened. I say `probably' the same because
I don't have witness enabled and I also don't have debug symbols for
vboxdrv.ko so the backtrace looks a bit different:
..
Unread portion of the kernel message buffer:
