Hi everyone, after I installed virtualbox, when I compile the kernel
and execute "make modules_install", the message appears:

and when I execute "modprobe vboxvideo", it saied
FATAL: Error inserting vboxvideo
(/lib/modules/2.6.33-gentoo-r2/misc/vboxvideo.ko): Unknown symbol in
module, or unknown parameter (see dmesg)
the output of dmesg is :
vboxvideo: Unknown symbol drm_open
vboxvideo: Unknown symbol drm_fasync
vboxvideo: Unknown symbol drm_poll
vboxvideo: Unknown symbol drm_core_get_reg_ofs
vboxvideo: Unknown symbol drm_ioctl

vboxvideo: Unknown symbol drm_init
vboxvideo: Unknown symbol drm_vblank_init
vboxvideo: Unknown symbol drm_mmap
vboxvideo: Unknown symbol drm_core_reclaim_buffers
vboxvideo: Unknown symbol drm_release
But when I use Virtualbox, all things are normal, I wanna know why
there are so many warnings, and why I cannot modprobe vboxvideo
Does it because my kernel didn't include DRM?
Many thanks
I don't know anything about virtualbox but are you sure you have the
symlink pointing to the running kernel? I mention because it sounds
like something I would do. ;-)
