This sounds like an interesting solution... Can you post a link to picture showing this particular setup? :-P scnr
Bah. :)
It could be some hardware issue, if there is some conflict with two cards.. But I have tried both cards in all PCI slots, no difference there.
With both cards installed, load the budget and the budget-ci modules and then take a look at the dmesg output and see what it says.
Actually both cards use budget-ci, the other card just doesn't have the physical connector although it has a place for it in the PCB. The cards look very similar, but newer card has tda10046 and older tda10045 frontend.. Both have saa7146 pci chip.
Here's dmesg output, looks ok to me:
saa7146: register extension 'budget_ci dvb'. PCI: Found IRQ 11 for device 0000:02:05.0 PCI: Sharing IRQ 11 with 0000:00:0d.0 saa7146: found saa7146 @ mem e0974c00 (revision 1, irq 11) (0x13c2,0x1012). saa7146 (0): dma buffer size 192512 DVB: registering new adapter (TT-Budget-T-CI PCI). adapter has MAC addr = 00:d0:5c:04:43:33 input: Budget-CI dvb ir receiver saa7146 (0) as /class/input/input1 budget_ci: CI interface initialised DVB: registering frontend 0 (Philips TDA10046H DVB-T)... dvb_ca adapter 0: DVB CAM detected and initialised successfully

Look into /proc/interrupts and see if both cards may be using the same interrupt.
Nope..
3: 64681 XT-PIC saa7146 (1) 11: 3565 XT-PIC saa7146 (0), eth0
Adapter 0 is the one that is working, so it doesn't matter that it shares interrupt with eth0. Adapter 1 seems to generate a lot of interrupts for some reason..
What happens if you append "acpi=off" and/or "noapic" to the kernel? >
No difference..
One thing I noticed is that after a reboot, working card always has valid firmware, but non-working card's firmware must always be re-uploaded.. So the firmware gets corrupted somehow?
Also I tried to tune channels with "tzap". It "works" for both cards, but the other card never reports FE_HAS_LOCK and "ber" is very high. Looks pretty much the same as if the antenna was unplugged.. (it's not..) :)
Perhaps there is some problem having tda10045 and tda10046 in same system? After all, both are handled by the same tda1004x module..
