Hello,
I'm having some problems with my Terratec Cinergy C PCI DVB-C card. I
installed the mantis driver via DKMS, following the instructions at
http://www.linuxtv.org/wiki/index.php/Mantis_with_DKMS
The card is recognized, and it even works, but after a while
(typically 5 to 20 minutes) the card no longer tunes to any channels
and the scan command no longer works. If I modprobe -r and modprobe -i
the mantis module everything works again for a while, until the same
thing happens. So I assume this is something driver related? Any help
would be appreciated, I will be happy to provide any additional
information if needed.
Some information that may or may not be useful:

PS. The repository I checked out from

was (and still is) broken. A bad merge in v4l/Kconfig, lines 3164-3168.
