As soon as that happens the messages repeat= s my network drops and no keyboard input. However the message repeats and = it doesn=92t appear that the system has fully locked up otherwise.

Perhaps some kind of dump proc= edure? Or is there a way I can confirm that freebsd can properly see and u= tilize the VT-D extensions. VirtualBox runs fine with the VT extensions en= abled.

It is available here: http://people.freebsd.org/~neel/patches/bhyve_iommu_init.patch Could you give it a spin and see if it helps with the ASUS system? best Neel > Joe Maloney > > _______________________________________________ > freebsd-virtualization@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-virtualization > To unsubscribe, send any mail to "freebsd-virtualization-unsubscribe@free= bsd.org"
