Hi Jody, I managed to compile a 2.6.12-rc2 kernel on amd64 running pure64/sid. I used Andrew Morton's mm3 patch and your RT-rlimits patch. i installed and rebooted into the new kernel. I got the libpam packages (libpam0g-dev libpam-cracklib libpam-doc) with apt-get from pure64 repository. Already had libpam0g, libpam-modules, libpam-runtime. How do I apply your patch to this PAM stuff. I don't really know where to start. Also, I couldn't find the sources, where should I look? Thanks, Norv
