[linux-dvb] kernel oops with Terratec Cinergy C

[linux-dvb] kernel oops with Terratec Cinergy C

[Philipp Kolmann]

Hi,

I am new to linux-dvb so please excuse if this has been discussed before here.

I just got myself today a Terratec Cinergy C DVB-C PCI Card:
05:01.0 Multimedia controller: Twinhan Technology Co. Ltd Mantis DTV PCI
Bridge Controller [Ver 1.0] (rev 01)

I have read some pages and found the mantis hg tree at
http://jusst.de/hg/mantis/ and compiled it for my debian unstable box
(2.6.24-1-686).

Now the card is detected and I started w_scan. After some time, I got the
following Kernel oops:

If there is anything I can test, just tell me.

Thanks

Re: [linux-dvb] kernel oops with Terratec Cinergy C

[Philipp Kolmann]

Just for the reference. I managed to get the card working yesterday with an
older verion of the mantis drivers. It seems that the dma issue came up with
the CA stuff.

Thanks
Philipp
