I have a question that has been bothering me for quite awhile.  I thought that 
at some point it might be addressed in one of the many driver versions, but 
it looks like it may be a problem that only I care about.

The problem is that, for all driver versions after 0.2.0-rc3g (in both the 0.2 
and 0.3 branches), I get interrupt errors as well as ivtv interrupts 
in /proc/interrupts even if I do not try to capture from my PVR-250.  This 
does not seem to affect my ability to capture properly, and the captured mpeg 
seems fine.  It just bugs me that a) I am getting constant interrupt errors 
and b) apparently the driver is throwing interrupts even if it is not 
"active".

Now, you may say, why is this a problem?  "Just use 0.2.0-rc3g is you don't 
want to see these interrupts and leave us alone".  I would, but there was a 
patch (0.2.0-rc3k - patch from Anduin Withers, fixes i2c changes in kernel) 
that keeps the driver compatible with kernels beyond 2.6.10.  I tried 
backporting this patch but was not entirely successful.  Applying this patch 
to rc3g stops the interrupt problems but forces me to specify a tuner type 
because it breaks tuner type auto detection.  I would try to find out exactly 
what caused this problem, but I believe it was introduced in rc3i and the 
diff from rc3h to rc3i is basically the entire driver.

So, what am I asking?  Do other people see this problem?  Is anyone else 
bothered by it?  Can someone who knows more than I do (basically, most anyone 
out there) take a look and see if there is an easy fix for this?  I know from 
reading the list that there is now a roadmap to kernel inclusion for the 
driver.  I think this is not a huge problem, but I believe it should be 
resolved prior to a version of the driver becoming part of a kernel release.

Feedback is welcome.  Please let me know if more info is required.

P. S. My config:

Asus A7V8X-X mobo
PVR-250 NTSC (tuner type 2)
FC3
Kernel 2.6.10-1.770_FC3 (current, testing 2.6.12--1.1372_FC3)
ivtv-0.2.0-rc3g (tried almost all version after in 0.2 as well as 0.3 
branches)
