 error)

Well, this isn't good...

After booting the new kernel, I get errors trying to do vfio passthrough:

qemu-8.2-system-x86_64: vfio: Cannot reset device 0000:14:00.3, no available reset mechanism.
qemu-8.2-system-x86_64: vfio: Cannot reset device 0000:14:00.2, no available reset mechanism.
qemu-8.2-system-x86_64: vfio: Cannot reset device 0000:14:00.1, no available reset mechanism.
qemu-8.2-system-x86_64: vfio: Cannot reset device 0000:14:00.0, no available reset mechanism.

Anyone have any ideas?
