Hi all,

I'm having a problem with the ASUSTeK P7131 Dual (an saa7134 based dvb 
card) pci capture card's remote IR controller , it's handled pretty well 
with latest linuxtv drivers, however after a while the IR remote stop 
responding completely, and unloading/reloading the whole dvb framework 
modules doesn't get it back working. Everything else still works  (that 
is dvb-t still works properly, I haven't used the analogic capturing 
features so far)

I tried to turn on debugging informations in the saa7134-input module, 
but nothing special appears in there, before or after the IR remote 
stops working.


If you have a few pointers as to what I could try to debug the problem, 
I'd be very happy. As far as I understand, that specific IR driver uses 
an IRQ, so maybe that IRQ stop working for some reason ?

Here are more informations on the specific model from dmesg, this is the 
1043:4876 model :
