I have no shares. Can I somehow try to umount everything in mtab? I'm not
familiar with the internal workings of mtab. I will read a bit. Also the
only thing I assume could be hanging is my external HD which I disconnected
having no effect on the problem behavior. Still I reported that my /boot
partition was being mounted and listed on kde file manager (forgot its
name) which was not default behavior. So could be the case that /boot is
hanging my shoutdown? I don't get the reason umount -a && shutdown -h now
did not do the trick.

I ask gently again if you could inform me why did the "magic reboot" did
work while shutdown did not.
