[vfio-users] new video card. vm wont boot

[Roger Lawhorn]

This appears to be the navi reset bug.
Supposedly kernel 5.4 fixes this.
However, I am not able to upgrade beyond kernel 5.3.
Kernel 5.4 gets a raid error when trying to read my encryption key and I 
cannot type my passphrase in order to get booted.
Same with higher kernels.
Alas.

I can sit and watch qemu reset endlessly while trying to boot the vm.
