Hey all, I think I am doing something really stupid depmod reports that bttv has unresolved vmalloc_to_page function Here is the exact commands I used (on a test RH 6.2 machine). tar -xvzf linux-2.4.18.tar.gz patch -p0 <patch-2.4.19-pre4 patch -p0 <01_(patch from Gerd's site) patch -p0 <03_(other patch from Gerd) (go into directory and build kernel with video for linux but not bttv) (reboot) go into bttv-0.3.38, compile and then make install Here I am told that depmod fails with errors reported above. I KNOW that 2.4.19-pre4 has the symbol in it, I tried copying the System.map from /usr/src/(where I built the kernel) to /boot/System.map, and depmod reports the same problem. Any ideas? Chris
