[linux-dvb] Avermedia DVB-T oops

[Wayne Parrott <wayne_p@pacific.net.au>]

Hi There,
I am trying to get my avermedia dvb-t working with kernel 2.6.0test9
but i get an oops message when i run scan.
I am using the dvb-kernel CVS, are there any other changes that are
required?
Here are the relevent bits of dmesg

I did some debugging and the problem is the access to the sp887x_firm
variable on this line
memcpy(&buf[2], &sp887x_firm[i], c);
Any access to this variable causes the oops.
If I comment out the loop to set up the firmware scan and xine will  
work fine, but i'm guessing that is because it is set up from windows  
already.

Any ideas why it is oopsing?

Thanks
Wayne
