So... I do not have a dual boot on my machine, but I suppose the 'Error
parsing PCC subspaces from PCCT', accompanies by quite frequent and
random system freezes (I have to REISUB) is due to the the following
lines:
~$ sudo efibootmgr -v | grep -i windows

I am quite new to Linux Ubuntu and have to admit being kind of startled
by the Windows Boot Manager running on my system despite using a clean
install of Ubuntu on a factory-new SSD...?
I will be glad to provide further information, if necessarry.
Thank You very much in advance.
