Afraid I can't easily at present. Upgraded the kernel to 2.6.6 and now
my DVB card won't work at all. It was working, but would time out with 2.6.5

I think it's to do with the changes to the BTTV driver, but I can't
really tell. 

How would I go about collecting more information, so as to be able to
submit a proper bug report?

Now my logs look like this :(

It looks as though this might be the change (from the 2.6.6 changelog);

[PATCH] v4l: bttv driver update
From: Gerd Knorr <kraxel at bytesex.org>
        
This patch updates the bttv driver.  Changes:
        
          (1) several card-specific tweaks.
            (2) make software vs. hardware i2c configurable per TV
          card.
            (3) reinitialize image parameters after chip reset.
              (4) make bttv quite by default on frame drops.
                (5) new insmod option: "debug_latency=1" to enable
          frame drop
                debug messages.
                
                bttv is quite sensitive to irq latencies, especially
                when capturing both
                video and vbi.  There are several reports about
                problems due to this, I don't
                see that on my machines through.  (5) dumps a
                stracktrace if the driver
                thinks the frame drop is is caused by high latencies
                as experiment, lets see
                whenever that helps ...
