Thanks for the very valuable information here! I managed to reproduce a
very similar crash in Qemu by simulating your hard drive layout:

I'm using manual partitioning with the first partition mounted as the
ESP partition and the sixth partition as the root directory.

The backtrace and the messages log file are attached. I'll try to find
some spare time to understand what's going on.

Thanks,

Mathieu
