Subject: No subsystem id (and therefore no cx88_dvb loaded) after reboot
Date: Tue, 17 Mar 2009 22:59:14 +1100 [thread overview]
Message-ID: <e0f27036e7a5af1cc8e8a725b522593b@localhost> (raw)
I'm looking for some pointers on debugging a problem with my DVICO
FusionHDTV Hybrid DVB-T card.
The device was working perfectly prior to a reconfiguration of my machine,
kernel upgrade etc...
Now, on a cold start everything seems to start smoothly but I can't tune
channels.
Then, after a reboot the device is not detected due to "invalid subsystem
id". As below lspci reports no subsystem information at all.
Comparing the lspci output seems to be around the "Region 0: Memory at
ee000000 v de000000", but I'm not
sure what this means, and whether fixing the reboot problem will fix the
channel tuning problem.
