Shutdown hang with MA401 configured

Hello! I’m a unit newbie trying to get QNX fully functional. I’m using a Netgear MA401 network card and have successfully gotten it running with help from this article:

Basically I’m using somethign like this in the rc.local file:

slay io-net
/sbin/io-net -p tcpip -d /lib/dll/ channel=10, ssid=linksys, station=qnx,verbose
sleep 5
/sbin/ifconfig en0 netmask
/sbin/route flush
/sbin/route add

The issue is that now whenever I shut down, the shutdown procedure consistently hangs at enum-pccard. I have to manully power off at that point.

I know I should probably put the init for the card into the enum overrides, but I haven’t figured out how to do that (ven and dev options, etc). I’m actually surprised that there isn’t an enum already for the prism driver.

Can anyone point me in the right direction on how to get the system to shut down correctly? Thanks.
