There's something in your partition table that throws the dissector
off. Next step would be to debug this with gdb, i.e. run:

sudo SYSTEMD_LOG_LEVEL=debug gdb ---args /usr/lib/systemd/systemd-dissect /dev/vda

after installing debug symbols, then step through this, and figure out
where this issue happens.

Or in other words: this is a bug, and needs to be tracked down like a
bug hence...
