This little problem is because the mmap() interfaces have changed under RH9. Basically as you noticed under RH9 the driver now takes 5 arguments instead of 4. What's happend is that when you've applied the updated bttv patch its put the orignal interface calls back. This should be fairly simple to fix. Make sure the mmap() function definition looks like this: static int do_bttv_mmap(struct vm_area_struct *vma, struct bttv *btv, const char *adr, unsigned long size) and then make sure any remap_page_range() calls have 'vma' as their first argument. Insert it if they don't. That's all that there should be to it. I had a similar problem with the usbvision drivers under RH9, but I managed to get them working without too much hassle. Cameron
