Not too odd, unfortunately. The cx88 is a pretty old card. The last
time I did any work on it I had to dig around quite a bit to even find
a PC that still had a PCI slot for testing/debug.
It would be very useful to know if you see any difference in behavior
with the stock command line DVB tools. Does azap report different
results between the two kernels?
My guess is that either the DVBv3 API got broken through some subtle
change in error handling, or it's something specific to that hardware
design (i.e. cx88 with the lgdt3303).
