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.

I experience similar problem with HVR4000 Lite cards that we have in the
lab. The card can't tune after cold boot, but a reboot will fix the
problem. I will check whether it has the similar invalid subsystem id
problem.

Unfortunately, I can't reproduce the cold boot tuning problem now. We'll
send syslog information if our partner universities report the similar
issue. Sorry.

currently, though we're working on a commercial implementation of the
RTP profile.
If you're interested in the GPL'ed UDP profile code, we can email it to
you in a week or two (we'll eventually make it available on our website
as well, but currently it needs to be cleaned up a bit).
