Trying to modprobe saa7134 with this card results in a hanging modprobe
process.
dmesg gets:

At that point, modprobe hangs; I can still use the box in other ttys, but [of
course] the saa7134 card doesn't work.
This is reproducable at least with with 2.6.10-rc3-mm1, 2.6.10 and 2.6.10-ac1;
the card used to work with earlier releases (I can't remember the last
version that worked though, haven't used it for a while).

I've reported this before:
http://lkml.org/lkml/2004/11/17/275
The patch that Rusty posted doesn't seem to have it made into
module-init-tools-3.1. Bummer :-(
The Bug in saa7134-core.c doesn't seem to have been addressed yet, so
I suggest the following patch as a temporary measure:

Because it was a dumb idea, as your reply showed. You can't load any
dependent modules because this module is not initialized yet (what if
you loaded a module that depended on you, then failed your
initialization?). Gerd has the real fix, IIRC.
Rusty.

Yeah, but IMHO it would be better if modprobe would bail out
with an error instead of just hanging. For me hotplug
loads the drivers at boot time and it's a bad good thing if
the whole boot process hangs.
