Can't load vboxvfs in x64 ubuntu guest

[Valafar]

I recently upgraded from 2.0.2 x64 to 2.0.4 x64 and installed Kubuntu 8.10 x64 as guest (I also have kubuntu x86 8.04).

When trying to mount shared folder in former:

$ sudo mount -t vboxsf vbox /mnt/virtualbox => /sbin/mount.vboxsf: mounting failed with the error: No such device

And when trying modprobe:

$ sudo modprobe vboxvfs => FATAL: Error inserting vboxvfs (/lib/modules/2.6.27-7-generic/misc/vboxvfs.ko): Unknown symbol in module, or unknown parameter (see dmesg)

Mounting shared folders in latter, x86 kubuntu guest, works fine.

There's the output from dmesg as attachment.

Please could you update your 8.10 Kubuntu to the latest packages and then resinstall the guest additions? I seems that the kernel headers the vboxvfs module was compiled with did not match the kernel.

I try what was suggested by frank but that did not work for me.

Sorry for not mentioning earlier: We found the problem. Please have a look at #2550, I've described a workaround there.
