Problem with 2nd DVB-S PCI card (Technisat Skystar 2)

He guys,

I´m running Mythbuntu 10.04 Beta with the latest updates. On my system, I have installed 2 USB DVB-T Tuners and 2 DVB-S PCI Tuners (Technisat Skystar 2) but the second one does not show up in /dev/dvb!

So the situation in /dev/dvb is as follows:

The first Technisat DVB-S tuner (/dev/dvb/adapter0)
The two usb dvb-t tuners (/dev/dvb/adapter1 and /dev/dvb/adapter2)

The second DVB-S tuner is simply not there.

lspci is fine so far:

Maybe it´s a more general problem with PCI..?

Strange detail: I had to install mythbuntu a few times and when I installed it for the first time, all tuners showed up like they should.

Thanks for your help,

natty

Do they both work by themselves ? Unplug one and try it, then replug it and remove the other one. It's not unknown for things to die. Use the same slots you are using now though. Also you can check the slots. If both cards work in the same slot, but neither work in the other slot then it's a pci issue.

Also, DVB tends to take a lot out of the buss (overloads the available transport space) which may be a problem. I only have 2 pci DVB-T cards but I have to have them in widely spaced slots rather than right next to each other, or else they may share one interrupt. I can see that your nvidia card is using the same interrupt (16) as the non-working DVB-S card. Try the card in a different slot. Slot 1 usually shares an interrupt with AGP.
