Just about the only thing that could cause this would be an i2c timing
change. Use the v4l-dvb repository, edit file ivtv-i2c.c, search for
this line:
.udelay = 5,
and replace the 5 with 10. Try again and see if this solves the problem.
Please let me know the result.
The i2c timings were changed to speed up the firmware load, but this
might have introduced problems in this area.
