Public bug reported:
I try to pass-through nvidia 1060 6gb card, which is connected via
ExpressCard (EXP-GDC converter).
I can successfully run my virtual machine without pass-through, but when
I try to add the devices, qemu crashes.

My laptop is Thinkpad x230, that runs on Intel(R) Core(TM) i5-3320M CPU @

I run 5.8.6-1-MANJARO kernel and run QEMU emulator version 5.1.0.
Thank you for your attention. I'd love to provide more information, but
I don't know what else matters.
