Yes, I just proceeded re-check both builds with removing obj dir each time and I still see the problem starting with r274914.

Also restoring files like that on latest head makes things happy (no panics):
svnlite up -r274913 sys/kern/vfs_default.c sys/kern/vnode_if.src sys/sys/buf.h sys/sys/vnode.h sys/ufs/ffs/ffs_vnops.c sys/vm/swap_pager.c sys/vm/vm_pager.h sys/vm/vnode_pager.c sys/vm/vnode_pager.h
