To the maintainer of the af9015, af9013 modules: A recent kernel (but the problem had been the same with older kernels): 2.6.32-22-generic #36-Ubuntu SMP Thu Jun 3 22:02:19 UTC 2010 i686 GNU/Linux Latest (as of yesterday) checkout of v4l-dvb (but the problem had been the same with older checkouts). Dual channel USB DVB-T stick initialized ok, but regularly the stick does not tune properly on one of the two channels and the kernel shows these error messages at the same time: [14410.717905] af9015: command failed:2 [14410.717913] af9013: I2C read failed reg:d330 [18208.030546] af9015: command failed:2 [18208.030554] af9013: I2C read failed reg:d2e6 I'm willing to help debug. Who is the maintainer of af9015, af9013?
