>Description:
System freezes when "ifconfig"-ing any ATM-Interfaces. Nor reaction on any
keypress, nor ACPI-Events (when trying NATM).
With HARP kernel panics and reboots

<f29tq0$2g09$1 at geiz-ist-geil.priv.at>

"panic-output":
panic: ipatm_nifstat: setaddr missing ip_nif  

System is a Dual-Core opteron (AMD), i386 FreeBSD-Flavour

Card getd detected and ist displayed as Interface (ifconfig), even reports
Carrier to console when (un)plugging from the Network

>How-To-Repeat:
Plug a ProSum ATM-155 card in, compile with "device patm" (and ATM-support),
start up HARP or NATM. With the first "ifconfig" (with IP-Settings) on
an ATM-Interface System goes boom.
>Fix:
Currently none kown.
