Haupage 2250 / saa7164 kernel errors

About once a day, my tuner stops working and my logs fill up with the following messages:

2015-01-28T20:40:23.736478-08:00 mediapc kernel: [169020.845484] saa7164_cmd_send() No free sequences
2015-01-28T20:40:23.736480-08:00 mediapc kernel: [169020.845486] saa7164_api_i2c_read() error, ret(1) = 0xc
2015-01-28T20:40:23.736483-08:00 mediapc kernel: [169020.845489] s5h1411_readreg: readreg error (ret == -5)

I've seen a couple other posts about it in this mailing list with no responses yet. Does anybody have an idea of why this could be happening, or any suggestions on what I could try to debug this issue?

Thanks,

David
