The FreeBSD client no longer has its own vnodes. It uses the system pool now. But that has introduced a slew of new bugs. Client bugs seem to fall into two broad classes, vnode ref count screwups, and vnode locking screwups. These usually manifest themselves as "unclean vnode" panics, "locking against myself" panics, and hangs. Turning on WITNESS can help to track down some of them. Part of this is due to the code borrowed from OpenBSD, which has a different set of vnode locking rules. If anyone has patches, I urge you to send them here rather than fork the source.help
