intel-microcode: regressions on Haswell, Broadwell (crashes/reboots) and Kaby Lake (sleep-to-ram)

No problems here for me.  apt-listbugs gave me the heads up and I did  (as root) "apt-mark hold intel-microcode" and I will wait and see.

Systems that are sparky testing or debian testing for me are both intel atoms and are supposedly immune to Meltdown and Spectre.  So one update I can really wait on.

Debian BTS now says it is fixed.

apt-mark unhold     ## for me.
