You do a recursive halving of time period when a particular problem appeared. For example you know that problem appeared before yesterday and day of 5.3-RELEASE. You obtain kernel sources for a middle of that period using cvsup or cvs, build kernel and test it. If problem persists you half the first half of the period and build another kernel. If problem disappaers on this kernel, then you half second half of the period. -- Totus tuus, Glebius. GLEBIUS-RIPN GLEB-RIPE
