Dual slot PCI riser messes up ivtv

[Islam Amer <pharon@gmail.com>]

Hello everyone.

I am trying to build a settop box with two cards, a PVR-150 and a DVB
card. The mini-ITX motherboard has only one PCI slot, so I bought an
active PCI riser.

First I tried with two cheap lifeview cards on the riser and they
worked.
 
The PVR-150 is working fine alone, and so does the DVB card. But when I
use them with the riser nothing works.

Here's the debugging output when using both cards on the PCI riser.

It seems to me that it is initialised correctly. But when I try to use
tvtime it gives this error :

videoinput: Card failed to allocate capture buffers: Invalid argument

Mplayer Just crashes.

The other card is messed up as well :

I am using ubuntu feisty, and the situation is the same with the distro
provided kernel 2.6.20-16-generic and ivtv-0.10.2

I also compiled ivtv-0.10.3 and nothing changed.

I even compiled a 2.6.22-rc5 since I found out that the ivtv module got
merged in mainline.

I emailed this to ivtv mailing list as well as the linux-dvb mailing
list, but I thought I would re-post here in case the support team moved
after merging with mainline.

Can anyone please point me to the right way ?

Thank you.
