After merging the newest virtualbox-modules and virtualbox-bin I'm getting a failure to modprobe with the following messages: vboxdrv: Unknown symbol add_preempt_count vboxdrv: Unknown symbol debug_smp_processor_id vboxdrv: Unknown symbol sub_preempt_count Thinking it was a problem with the newest modules, I went back to the old 2.2.0 modules and got the same errors. I'm using a 2.6.27 vanilla kernel kernel Reproducible: Always Steps to Reproduce: 1. emerge virtualbox-modules 2. emerge virtualbox-bin 3. modprobe vboxdrv and check dmesg for error. Actual Results: modprobe fails and says to check dmesg for the full error message. Expected Results: The module would insert without errors.

You need to have the same kernel config in the configuration ( /usr/src/linux ) and in the active kernel. Otherwise Bad Things May Happen :) I don't think this is a virtualbox issue, if you recompile your kernel with the current config, recompile the virtualbox modules and then reboot with that new kernel the issue should go away. If not please reopen this bug.
