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.



Running mythbuntu 8.10

lspci -vvnn after cold start
