[mythtv-users] Card not ready

[James]

Hi
I changed my backend from an i7 to rysan. (Lightning, magic smoke etc)
All went smoothly *except* the cards are not ready when mythtv starts.

This always worked on the i7
-------- mythbackend.service
[Unit]
Description=MythTV backend service
After=network.target mysql.service
Requires=mysql.service
Wants=apache2.service

[Service]
Type=simple
EnvironmentFile=/etc/sysconfig/mythbackend
User=jam
Group=video
ExecStart=/usr/local/bin/mythbackend --logpath /var/log/mythtv $MYTHBACKEND_OPTIONS
--------

At the macro level I know what to do, it's the detail ...
does instantiation of /dev/dvb/adaperN mean the card IS ready or SOON-WILL-BE ?

Any suggestions?

Thanks
James
