Hello !
This problems appears about 4-6 months ago after updating of -CURRENT hos=

Unable to boot host with nvidia_load=3D"YES" in loader.conf because panic.
But when nvidia driver loads manually via kldload, everything OK.
Nvidia driver version is 310.44 at this moment, but problem was and on =20
