Please run as root:
update-initramfs -u -kall
Power off the computer (shutdown -h now). You MUST cold-boot to apply
the "microcode downgrade" properly.
Then power up the computer, let the operating system boot, and send to
this bug report the output of:
cat /proc/cpuinfo
journalctl -k -b | grep -i microcode
iucode_tool -SL -tr /boot/initrd.img*
(you might need to be root to do the above).
After that, try to reboot (shutdown -r now) and tell us if it worked, or
hang.
Details:
The update-initramfs -u -kall *SHOULD* ensure the microcode update table
is replaced. We use the iucode_tool -tr command to cross-check that.
The other commands shall tell us what microcode revision is running on
the processor, and whether it was updated on boot by the kernel or the
BIOS/UEFI.
