Well, ivtv-0.4.1 switched to the hotplug mechanism. My guess the problem
is with that.
Edit ivtv-firmware.c, look for CONFIG_FW_LOADER and replace that #if
with #if 0. Do the same in ivtv-driver.h and cx25840.h.
Recompile, install and test. If it now works again, then it is the new
hotplug stuff that breaks things. But why don't I get the same
problems? Weird.
If it is hotplug related and if you are handy with C, then can you
perhaps do some tests? I was thinking of hacking ivtv-firmware.c so
that the firmware load routines so a simple sum of all the bytes in the
firmware and then show the grand total when done. I'd be very
interested to see if there are any difference between the hotplug and
non-hotplug cases.
