Journalctl log

I got this problem since a while with my laptop, by some reason, starting Qemu with VGA passthrough randomly generates a kernel panic with a total freeze of my computer.

I just attached a log from systemd (filtered with only useful data)

Why this panic is happening? Reporting it as BUG because the log mention it, no idea if this is my laptop faulty.
