I grabbed an external USB drive from an Intel machine and put it to an AMD

using it to boot directly from it like:

On the AMD machine this doesn't work and I get a lot of:
ivhd0: EVT INTR 45 Status:0x1a EVT Head:0xfb0 Tail:0x430]^M
[CMD Total 0xaf] Tail:0xaf0, Head:0xaf0.^M

Is this in theory supposed to work?
Yes.
Good.
Does this in any way depend on the USB
port used or are we simply working on the device node?
bhyve only uses the device node.
Also good.
Do you have passthru devices configured ? If so, are they under the same
controller that the USB device is on ?
I do.
And they did work fine without the raw disk (netbooting FreeBSD).
If I remove the passthru devices the Linux on the disk boots.
