I upgrade nvidia-driver to version 390.67-2 and I can boot without option  
"slab_common.usercopy_fallback".


nvidia-graphics-drivers (390.67-2) unstable; urgency=high

  * Add kmem_cache_create_usercopy.patch from Red Hat, fixing "Bad or missing
    usercopy whitelist? Kernel memory exposure attempt detected from SLUB
    object 'nvidia_stack_cache'" on Linux kernels that have disabled
    CONFIG_HARDENED_USERCOPY_FALLBACK (i.e. linux-image-4.16.0-2-* or newer).
    (Closes: #901919)
