Probably nothing. I just had the same issue as nemixer (and the same setup), and there was nothing matching "ox" in dmesg. Reinstalling virtualbox-ose and running "sudo /etc/init.d/vboxdrv start" again helped.
This may be a duplicate of Bug #153819 and Bug #154630 Please seperate nemixers' bug report from the initial creators (sebasmagri), as they seem to be completely different issues. -- Virtualbox OSE doesn't run in Ubuntu Gutsy Gibbon https://bugs.launchpad.net/bugs/153989 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
