Garry Dolley, you hit another bug. As I understood, the problem is inside io. When your OS flusches dirty page all read requests are frozen. If in this time freebsd tries to read from disk via DMA-channel it fails to do that as kvm cant read from disk. So freebsd thinks that disk is broken and reports this ERROR.
