[asterisk-users] [FreeBSD 6.3] Right-way to recover Zaptel?

[Vincent]

Hello

	I'm running Asterisk 1.4.20.1 on a FreeBSD that I compiled from the
Ports collection.

It's the second time I'm having an issue with a FXO card and/or the
Zaptel driver. I couldn't figure out what else to do, so I just
rebooted the server, but I'd like to know what happened, and whether
there's a less drastic solution.

Here's some infos:

===========
# /usr/local/etc/rc.d/zaptel stop

directory
kldunload: can't find file wcte11xp.ko: No such file or directory
kldunload: can't find file wct4xxp.ko: No such file or directory
kldunload: can't find file wct1xxp.ko: No such file or directory

Thanks for any tip.
