Hi Enrico,
your patch made it into the saa7134-20030922 snapshot. With this one I
get hard lockups on 2.6.0-test5 when I load all the driver modules and
then finally the saa7134. Can see that with a FV3K on a SiS 746fx and a
md9717 on a A7V133. Both kernel are preempt and acpi enabled and using
nvidia 4496. With the saa7134-20030910 both are fine, but yes it seems
there is no input coming through from the remote. For the freezes I have
absolutely nothing on debug info in the logs. Only "Linux video capture
interface: v1.00" and then nothing. Can you confirm, if it works or not
with your Cinergy 400?
Greetings
Hermann
