After the update to kernel 3.14 my laptop stopped suspending/hibernating properly. I have narrowed down the problem somewhat, but before I submit a bug upstream, I'd like to try and bisect the kernel to find exactly what broke things for me (and I suppose I might be asked by upstream to bisect the kernel anyway). I have never done this before, and I suppose there might be a few catches I should be aware of before I start what will be a time consuming process. My plan is to start with the current PKGBUILD for the kernel (or a PKGBUILD from AUR) and modify it a little for my needs. However I don't know if I should start with a kernel configuration file from the 3.13 series or if I can use the one that is used by the current kernel. I was thinking of making use of 'make localmodconfig' to cut down on the compilation time, but I don't know if there are any catches I should be aware of. Should I use 'make config' followed by 'make localmodconfig' or using only the later is ok? Can I compile the kernel on the same dir where I'm using 'git bisect' or is it advisable to clone that to a new dir and build in the new dir? In case compiling in place is ok, should I use 'make clean' before compiling a new kernel? Regarding patches, I suppose I shouldn't need to include any extra patches or are there any known needed patches required to build kernel 3.13? -- Mauro Santos
