:Hi, just gave it a try on VKERNEL (-n 2) built from the source
:DragonFly-2.3.0.555.gb364b with your patch applied. It panicked just
:before login prompt. Booting into single user mode is OK, but issuing
:`reboot' command from single user prompt also triggers a similarly
:looking panic.

Ok, patch #3 is up:
fetch http://apollo.backplane.com/DFlyMisc/revoke03.patch
The only change I made was to move the vn_unlock() on line
346 of kern/tty.c from after the revoke to before the revoke:
if (vp->v_flag & VCTTYISOPEN) {
vclrflags(vp, VCTTYISOPEN);
VOP_CLOSE(vp, FREAD|FWRITE);
}
vn_unlock(vp); <<<<<<<<<<<<<<< vn_unlock moved to here
if (dorevoke)
vrevoke(vp, proc0.p_ucred);
<<<<<<<<<<<<<<< used to be here
vdrop(vp);
