[linux-dvb] saa7134 bug in 64 bits system

Hi,

I located the problem by doing the following experiment. I boot the 
kernel with only 2G installed and everything worked fine. No if you come 
back to the initial configuration it crash badly. A little digging on 
google gave some nice information. It seems that this problem is the 
combination of a bug in the bios and/or in the pci resource allocation. 
So I will report this to the kernel list.

I will try that.

Thanks for the help
