To provide just another data point:
On my machine the interupt assignment didn't change due to the system
upgrade from SuSE 7.1/Kernel 2.2.19/vdr 1.0.4 to the c't VDR Distro
I'm using right now.  

I've saa7146(0) on IRQ 11 and saa7146(1) on IRQ 9.  Both interupts are 
exclusively assigned to the DVB-S Rev. 1.3 cards.  No IRQ sharing.  

Since rebooting fixes the problem for a while, I also can't believe, that 
the problem is caused by a hardware failure in one of my cards.  It is
very unlikely that one of the cards, which used to work flawlessly since
February 2001 broke just at the moment, when I upgraded the VDR software.  
Since other people reported the same kind of problems here, this seems
to be even more unlikely.

Here is just another part of my log from yesterday:

So at the moment the problem occurs on my machine a daily basis.  
This is annoying.  (Please don't misunderstand me: I'm still very 
thankful about what Klaus and the Metzler Bros.
and all you other guys have accomplished here).

Nevertheless I don't want to go back to VDR 1.0.4.  

So I would like to know, if I better should first try to change from
the http://heise.de source/ vdr 1.2.2-5woody1 package distributed with
the c't VDR distro to the recently released 1.2.5 or 1.2.6 or whether
I should first starting to build an unstripped binary of vdr 1.2.2
and try to attach with gdb to the VDR thread, whenever the problem
happens next time.  But what to do then?  Where to look?  If it
is problem within the firmware or driver, debugging in VDR wouldn't
help to gather any useful information.

I've had a look at the vdr-1.2.5_Old_CA_Descriptorhandling.diff
patch and I'm reluctant to apply it without understanding anything
what it does.  As has already been discussed here, it seems to change 
far to much at once.
