Public bug reported:
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/prod/fw/fw.iso,if=virtio,format=raw -drive file=/vms/prod/fw/swap,if=virtio,format=raw -drive file=/vms/prod/fw/fwdata.iso,if=virtio,format=raw -m 512 -nographic -kernel /data/kernels/vmlinuz-2.6.36-gentoo-r8 -append "root=/dev/vda console=ttyS0 earlyprintk=serial" -net nic,model=virtio,macaddr=DE:AD:BE:EF:2D:AD -net tap,ifname=tapfw0,script=/etc/qemu/qemu-ifup -device pci-assign,host=03:00.0

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

Triaging old bug tickets ... Can you still reproduce the issue with the
latest version of QEMU and the kernel, or could we close this bug
nowadays?
