Windows 7 x64 guest not running after upgrading from v0.7.8->v0.7.9

[maurizio-emmex]

Iohyve v0.7.9 runs the command :
/usr/sbin/bhyve -c 2 -H -w -m 6G -s 0,hostbridge -s '1,ahci-hd,/dev/zvol/pool2tb/iohyve/win7_maurizio/disk0,sectorsize=512' -s 2,virtio-net,tap1 -s '3,fbuf,tcp=0.0.0.0:5901,w=1280,h=1024' -s 31,lpc -l com1,/dev/nmdm0A -l bootrom,/iohyve/Firmware/BHYVE_UEFI.fd/BHYVE_UEFI.fd ioh-win7_maurizio
and after some seconds the VM will stop running.

Changing the ahci-hd slot from 1 to 4 the VM works. The modified command is:
/usr/sbin/bhyve -c 2 -H -w -m 6G -s 0,hostbridge -s '4,ahci-hd,/dev/zvol/pool2tb/iohyve/win7_maurizio/disk0,sectorsize=512' -s 2,virtio-net,tap1 -s '3,fbuf,tcp=0.0.0.0:5901,w=1280,h=1024' -s 31,lpc -l com1,/dev/nmdm0A -l bootrom,/iohyve/Firmware/BHYVE_UEFI.fd/BHYVE_UEFI.fd ioh-win7_maurizio
