the first things you should try is to triage the patches by
rolling them back and then adding them one at a time and
testing until you find which patch appears to introduce the
problem (or whether it exists in the baseline without any
patches). In most cases you can then try skipping that
patch and applying subsequent ones until you find more
problematic patches or you successfully apply the remainder.<o:p></o:p></span></p>
