Very well...

For those affected (i.e. if your HP Elitebook 840 G1 DOES have
halt/poweroff issues right now), please do this:

1. purge intel-microcode from the system:

    %aptitude purge intel-microcode

2. re-create the initramfs (should have been done by the purge, but
better safe than sorry):

    %update-initramfs -u

2a. ensure there are no lingering files that would cause issues:

    ls /lib/firmware/intel-ucode
    
    That directory must be empty, or not exist at all.

3. reboot.

4. try to shutdown.

If the problem persists, it is not intel-microcode's fault.

If the problem is fixed by removing intel-microcode, I will ask for
further details to narrow the issue down.
