What you say is quite correct.
However, my card is not known by the driver, and `card=3' has been working
for me all the while, with no problems at all. In any case, removing
`disable_ir=1' from the insmod options hides the problem for me. By the way,
that option was there since in an an earlier -rc, loading the driver without
it would cause an oops.
The option disable_ir is, in fact, a workaround. If this is not needed
anymore, this is a progress ;) Anyway, having an OOPS is really bad. We
should go further to avoid oops on it.
IR on some saa7134 cards are really a trouble. Sometimes, it just
generates lots of weird events, since you are gathering a generic io
port (GPIO) from hardware to generate keypressing. Using the wrong port
may generate troubles at the system, by sending wrong events to input.
With a wrong card, if somebody fixed the IR, it may broke for your
board.

I tried to reproduce your problem but i didn't succeed yet. I also think
that the IR support could be the problem. Card 3 defines a GPIO based
remote support. As Mauro mentioned above, this is - at least - dangerous
if you force this card type but you don't have a remote control or just a
different one. This type of remote can use a GPIO port of the SAA713x to
generate interrupts. If this pin is floating on your card, the driver can
just be flooded with IRQs. We should have a look whether we can prevent this
in the IRQ handler.
