Hi everyone, I am trying to compile a realtime kernel using this guide https://help.ubuntu.com/community/HowToVanillaKernelWithRealtimePreemption except I am using the 2.6.19 kernel instead of the 2.6.16 kernel as the guide says and I am using the 2.6.19-rt15 ingo patch instead of the 2.6.16-rt26. I am also applying the bootsplash patch bootsplash-3.1.6-2.6.18.diff. I have no problems patching the kernel source The only thing that I can't do is change the setting " *Processor type and features > High Resolution Timer resolution (nanoseconds)* to /1000/. " because I can't find it. I figured that it was just taken out of the kernel by the time 2.6.19 rolled around. However the compile fails with this error CC [M] lib/zlib_deflate/deflate_syms.o LD [M] lib/zlib_deflate/zlib_deflate.o Building modules, stage 2.
