[linux-dvb] Mantis and CAM problems

I have Terratec Cinergy C (dvb-c, 1822:4e35) card and when I try to use CAM I
just get TS continuity errors with vdr and cannot watch any channel. I'm using
latest driver from jusst.de/hg/mantis and it feels rather unstable at times
(previous versions crashed machine almost instantly with CAM...)

I can access CAM menu in vdr but after a while it says CAM not responding. If I
do rmmod & modprobe mantis after that I get "dvb_ca adapter 0: Invalid PC card
inserted :(". Removing & reattaching CAM doesn't do any better, after modprobe
mantis everything freezes and caps+scroll lock blink on the keyboard.

Something like ~150 TS continuity errors per sec. Video is pretty much garbage.
However if I remove CAM then everything works perfectly (except I can't watch
encrypted channels).
