You do know that the cx24123 module has nothing to do with the
Nova-t-500, don't you?

Would you have a DVB-S card in the system as well?

I do, and I have this module loaded too,  zero error message involving
it, and I'm not really losing any tuner in normal use.

I have
      * 1 Hauppauge Nova-t-500
      * 1 KWorld DVB-S 100
      * Gutsy 64-bit system
      * Ubuntu 2.6.22 kernel
      * Ubuntu updates+backports
      * Medibuntu
      * Mythbuntu's 0.20.2-fixes updates
      * a recent v4l-dvb tree compiles against the Ubuntu headers.

The only other USB device I am using is an RF transmitter for my
keyboard.

All (and I like documenting) details there:

Other than this issue, how's the stability of 0.21 in Hardy?
I'm itching... After al,l I ran Gutsy since alpha 2, for hardware
support reasons, but I have no real motivation apart from "I want to try
the latest and greatest" today.
