Hi,
As I faced problems with my Terratec Cinergy T PCIe Dual and was unable to solve it (yet), I recently purchased a used Hauppauge HVR-2200 PCIe dual tuner. I immediately ran into problems with the HVR-2200 as well, perfectly described here:
http://whirlpool.net.au/wiki/n54l_all_in_one
(scroll down or search "saa7164_cmd_send() No free sequences")
Basically, it starts working but after a while I get an "Event timed out" message and several i2c errors and VDR shuts down (some hours after reboot). As the web page mentions, I tested downgrading the PCIe bandwith from GEN2 to GEN1 without success. But after playing with different BIOS options, what did the trick was limiting the power-saving C-states. If I select "C7" as the maximum C-state, the card fails as described. After limiting the maximum C-state to "C6", it has been working for a whole weekend.
The HVR-2200 was also tested in a GA-H67MA-UD2H-B3 board with an G1610 Celeron, working without problems (although maximum C-state setup was not checked).
Probably the error is present in other saa7164 boards.
My VDR server is based on BayTrail J1900 (Asrock Q1900M).
PS: I'm still waiting for advice regarding my Cinergy T/cx23885 problems and debugging.
