    Assuming that those ??s are in the radeon module, this is a new
    backtrace to me. There's been one happening to some people where
    pmap_mapdev fails to allocate enough memory, which results in a panic,
    but I haven't been able to reproduce it here. My systems are working
    just fine on fresh -current :(
