>Description:
	
	Please remove or mark this port as ABSOLUTELY_BROKEN for systems
	running 4.11 because it instantly and badly crash.  Also crash on
	any machine with CURRENT and SMP (real dual processors, not HTT).

	I have a crash snapshot here (warning, about 320kB):

		ftp://ftp.torrini.org/pub/FreeBSD/zaptel_crash.jpg

	Never finished to syncing disks  :-(

	(note: before installing in my home server I tested pci card on a
	5.4-STABLE machine for 24 hours without any problem, maybe this is
	only a my problem with that 4.11 machine but a crash is a crash)


>How-To-Repeat:
	
	Buy an FXO board (new or used), it is a bare win modem pci card with
	a "known and supported" chip.  Install misc/zaptel.

	Note: up to 0.9 version of this port it doesn't compile.  Anyway now
	it forgot(?) to create required devices (with 5.4 or 6.0 and devfs
	there no need to do this step, obviously  :-).

	I don't know if device are usefull only for controlling this card or
	are really required also for starting up, anyway port doesn't create
	any device.  Now load kernel modules with provided .../rc.d script
	and machine instantly blow up.

>Fix:
	
	Add a big banner and stop it building and installing on 4.x or SMP.
