I see the problem on a Dell Inspiron. /proc/cpuinfo shows

vendor_id : GenuineIntel
cpu family : 6
model : 78
model name : Intel(R) Core(TM) i3-6100U CPU @ 2.30GHz
stepping : 3
microcode : 0xcc

A working version is

intel-microcode/now 3.20190618.0ubuntu0.16.04.1 amd64 [installed,upgradable to: 3.20201110.0ubuntu0.16.04.2]

Upgrading to 3.20201110.0ubuntu0.16.04.2 leads to a freeze on boot: after selecting
an entry in the grub menu there is a message about loading initramfs and the machine becomes
totally unresponsive, needs a hard poweroff. Rolling back to the previous version of intel-microcode restores system to a working state.
