Hello, what is this panic, got it just recently on a fresh -STABLE r332466: Apr 18 17:52:39 san1 kernel: vputx: usecount not zero for vnode Apr 18 17:52:39 san1 kernel: 0xfffff80f4d7d1760: tag devfs, type VCHR Apr 18 17:52:39 san1 kernel: usecount -1, writecount -1, refcount 0 "vputx: usecount not zero for vnode" can be fund in just one place, /usr/src/sys/kern/vfs_subr.c, and it's followed by the panic() syscall. Unfortunately, I have no crashdump of it (though I usually get crashdumps on this machine). Eugene.
