So much for avoiding a reboot for <b...@lordcow.org> (or whatever the correct address is -- that one bounced), but now it is beginning to look as if there may be a POLA violation at a lower level. Unless there are devices out there whose state can be changed by merely _reading_ (not writing) their configuration registers, I would not expect to need RDWR permission just to read them. _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
