Public bug reported:
The subject says it all:
When you update the ucode via the software store / center, the ucode as
reported by /proc/cpuinfo or
/sys/devices/system/cpu/cpu1/microcode/version doesn't match the
contents of /lib/firmware/intel-ucode for the corresponding revision
anymore (0x8e vs 0x84 on my i7-7560U). Thus, tools like iucode-tools get
confused and and useful utilities such as needrestart (which are in turn
relying on the correct functioning of iucode-tool) become broken in that
respect.
Workaround: fix package contents.
