there is something fishy going on :-)
with latest current,
the tests are run on a diskless host, and just after booting,
this is what i do:
newfs /dev/ad0s2a
mount /dev/ad0s2a /mnt-root
cd /mnt-root
rsh dev -n dump 0f - /c/4| restore rf -
panic: vn_finished_write: neg cnt
zeroing vnmp in getnewvnode, i get:
panic: getnewvnode: free vnode isn't
