Mint 19.3 (Cinnamon): Boot time!

Guys, I have a Samsung Series 3 Notebook, model NP300E5a-A05US and I recently upgraded from Mint 18.3 (Cinnamon) to Mint 19.3 (Cinnamon). Once booted, my laptop seems to run fine; in fact, I love the enhancements made since my previous installation of Mint 18.3 (Cinnamon).

My issue is boot time (see logs below):

$ systemd-analyze time
Startup finished in 7.310s (kernel) + 1min 57.249s (userspace) = 2min 4.560s
graphical.target reached after 46.787s in userspace

...it seems to hang here!

It seems that my Mint 18.3 installation booted much faster than my new Mint 19.3 installation, so my question is:

Is 2+ minutes boot time typical for my setup, or can I do better?

Thanks in advance, guys.
