vboxvideo module does not load

[Ronald Klop]

Thanks for the quick answer.

A recompile and kldload gave:

Jul 17 11:01:18 sjakie pkg-static[7338]: drm-devel-kmod-5.3.g20200710 deinstalled
Jul 17 11:01:19 sjakie pkg-static[7522]: drm-devel-kmod-5.3.g20200710 installed
Jul 17 11:02:07 sjakie kernel: link_elf_obj: symbol ttm_bo_dma_acc_size undefined
Jul 17 11:02:08 sjakie kernel: linker_load_file: /boot/modules/drm.ko - unsupported file type
Jul 17 11:02:08 sjakie kernel: KLD vboxvideo.ko: depends on drmn - not available or version mismatch
Jul 17 11:02:08 sjakie kernel: linker_load_file: /boot/modules/vboxvideo.ko - unsupported file type

Regards,
Ronald.
