Hi all, I made an attempt to custom build a kernel from the src.rpm. I followed the tutorial by Kevin Hobbs to complete the task. I have several questions with the build process. I did read a couple of tutorials before I actually build the kernel. 1. The build process failed at prep when I tried to build the binaries. rpmbuild -bb --target=i686 ~/rpmbuild/SPECS/kernel-2.*.spec . I followed the tutorial (Kernel Compilation Tutorial-Kevin Hobbs) step by step but could not build the kernerl. 2. So, I decided to build the binaries directly without rpmbuild -bp step. So i installed the src.rpm, then rpmbuild -bb ~/rpmbuild/SPECS/kernel-2.*.spec. This went smooth, except it took more than a couple of hours to build the rpms. So, is it normal for the build process to take this long? Why did the build process fail via the first method? (I should be able to provide more information on this, I do not have the tmp files right now) During the "make xconfig" I added ACPI /APM/ frequency scaling etc, and then built the rpms. However, after installing the newly build kernel and rebooting into this new kernel, I dont know if all of the above features were added or not. I could not find /proc/cpufreq, so I dont think I will be able to scale the cpu frequency? Thanks, shashank
