Thanks, I can confirm that the patches fix the crash for me.
The half-life of PV Solaris is still under the microsecond.

Btw. I have managed to get gdbsx going by replacing "/proc/xen/privcmd"
with "/dev/xen/privcmd".

Indeed, the state of Solaris is pretty bad:

- Solaris 11.3 under HVM boots, but the installer complains there
  are no local disks (which is not true, even device nodes are there
  under /dev/dsk/ ... )

- OpenIndiana (OI-hipster-text-20160421.iso as HVM) hangs after printing
  out the kernel version message

- SmartOS (smartos-20160428T170316Z.iso) 
  seems to work at first, but after the initial configuration
  it cannot bring the network interface up because its link
  state is unknown (tried model=e1000 and the default Realtek):

    [root at master0 ~]# dladm show-phys
    LINK         MEDIA                STATE     SPEED  DUPLEX   DEVICE
    e1000g0      Ethernet             unknown   0      half     e1000g0
