Thanks for the patches. If I'm not mistaken there are several variants
of this card: without upd* devices, only with upd64083 and with both
upd devices. Which one do you have?
Can you also show the dmesg output when ivtv loads?
Looking at the four patches, I would say that the only relevant patch is
the fix-probing patch. If you try it with only that one applied, does
it still work correct for you? Note that this patch will not work with
a KUROTOSIKOU card that has no upd* devices at all.
Can you also give me the kernel backtrace when you load ivtv with the
vanilla 2.6.26? I do not quite understand why it should crash.
