This is *not* fixed for Xenial. I had originally applied the workaround
in the bug description to get my computer to boot again. After seeing a
"fixed" status for this bug, I updated intel-microcode. After I
rebooted, my computer would not boot to the kernel which had the
microcode applied (4.4.0-122). It would only boot to the previous kernel
without the microcode (4.4.0-119).
