Hello,
I have a system with 2 (TT-Budget/WinTV-NOVA-CI PCI) cards, and in one
of them a CAM is present (canaldigitaal).
When i boot 2.6.10 i get CAM detected and initialised, see dmesg snip:

In this configuration MythTV 0.20 detects the CAM and tries
unsuccesfully to use it (i get no decryption).
When i boot 2.6.18 i get a dropped interrupt and CAM is not initialised:

Sep 21 11:07:34 satje dvb_ca adaptor 1: PC card did not respond :(
I have tried booting with pci=routeirq, this makes no difference.
Booting with irqpoll makes a difference: at detection of second card it
is a hard halt. No response from the system, except on HW reset.
In this configuration MythTV does not detect the CAM at all.
Any pointers to improvement greatly appreciated.
Cheers,
Rudy
