A DMA operation to the physical address 0x2c00000 is stopped by a IOMMU
and the kernel reports that. On Genode/Nova this typically means that
one forgot to load/use the device_pd [0]. Looking at the run script
there indeed the acpi driver and the device_pd application is missing.
The attached patch adds the missing pieces to the run script. Probably
there are some more run scripts out there missing the acpi driver and
device_pd for Genode/Nova.

This looks not good. I can't reproduce it here. Do you use the 14.11
Genode release with the nova kernel revision
2b4f2803218cf92e2982b47a370d60b18bb78a15 (r7) in
repos/base-nova/ports/nova.port ?
Cheers,
Alex.
