[mythtv-users] Hauppauge Nova-TD-500 fails, "DiB0070 I2C read failed"

[Dan]

Hi -

Our myth box with dual Hauppauge tuner works fine on boot, but then
overnight it often stops being able to tune to anything, meaning our
scheduled recordings fail. I think it happens about the same time as
this appears in /var/log/messages:

  Jun 28 01:51:18 boxname kernel: [105744.068079] DiB0070 I2C read failed

This is new since our mythbuntu dist-upgrade (to 10.04), meaning myth
went up to 0.23 but other things changed as well, of course.

dmesg | grep dvb

Anyone seen this, and/or any suggestions?

Thanks
