Hello,
This card (technisat cablestar hd 2 dvb-c) works fine when plugged
into a native PCI slot.
When I try it with a PCI-adapter I intend to use in mITX-builds there
doesn't seem
to be any data coming in through the tuner. The adapter is a
transparent bridge (with a
PEX 8112 chip) that goes into a 1xPCIe-slot and gets power through a
4-pin molex.
My guess is some kind of dma mapping incompatibility with the mantis
driver (s2-liplianin).
The card seems to initialize correctly, but doesn't work when the
tuner is put into action
(scandvb timeouts, dvbtraffic yields nothing). For the record, I've
tested the bridge with a
firewire card and that works fine.
Kernel is 2.6.32 (+the compiled drivers)
lspci for the bridge and the card:

I hear sometimes these bridges are not as transparent as they claim,
any pointers on what to look for?
