Check your dmesg/messages log for the following message:
vnode_pager: *** WARNING *** stale FS code in system.
If you have gotten this message, it means that you are trying to page
out to an FS that has stale code (ie: a local media FS that does not
support VOP_PUTPAGES). The FS needs corrected, so if you can identify
which one it is, I can do a patch for you (it's pretty easy to make
a VOP_{GET|PUT}PAGES to use the legacy code, but it must be explicitly
used; doing this will [later] enable user space FS module developement
to be stacked on top. The reason it's later is that there are still
151 imports for a non-stacking FS; the DDI/DKI for FS's needs a lot
of cleanup to get it to the point that it can be proxied to user space).
