Re: Bug#719623: linux-image-3.10-2-amd64: kernel panic on inserting DVB-T stick

I have just tested the patch against Debian's kernel sources linux-3.11~rc4 On first try, the kernel panic does not seem to occur with this kernel. So possible you solved it!

I took a quick look at the code and wonder if the problem is caused by an initial zero statistics message? This is all just a wild guess, but if it is correct, then the attached untested patch might fix it...
