I've been running a MythTV-box on top of Ubuntun Feisty for a year now without a hitch, using Technotrend C-1500 Budget card. Now I bought the new Terratec Cinergy C and installed the Mantis drivers I got from http://jusst.de/hg/mantis/summary. After this I got everything working fine in my Myth, but after a few days I there appeared to be a pattern where the whole machine just stops responding. This occurs every 12-24 hours and the source of it is quite hard to make out because obviously theres nothing in the logs.
I have tried with another Cinergy-card but the result is the same, it can't be a hardware problem. I dunno if the problem is the driver of the cinergy or perhaps the installation of mantis somehow broke the TT-card..
Help would be much appreaciated.
Here's dmeg from the box.

I'm using the EIT-info, so MythTV is doing this EITScanner quite often to check for new channel-info, so that may be the root of the problem.
Here's a log from mythbackend.log just before the machine once again stopped responding:
