[http://bugs.opensolaris.org/view_bug.do?bug_id=6565817] The vbi kernel module distributed with VirtualBox 2.2.2 seems to access data in kthread_t using the old offsets, so that it panics when we run on a build 114 (or newer) kernel. To reproduce the problem, try to start a virtualbox guest on an opensolaris build 114 (or newer) host.
