Bug Description
Hy,
the host system crashes completely, when i try to pass an physical device without boot option intel_iommu=on set. In older kernel versions you didn't have to pass that option.
I wonder if this can be easily checked by asking iommu state, avoiding a crash of the complete system.
My data:
cpu model: Intel(R) Core(TM) i7 CPU
qemu version: 2.4.1-r2
kernel version: 4.1.2 x86_64
command line:
qemu-system-x86_64 -enable-kvm -drive file=/vms/
There are also more detailed informations (if needed) here:

Thanks,
Antonios.
Sorry, i have to cancel this report.
The problem seems to be somewhere else. After some reboots the same issue came up again.
