As FreeBSD Stable is a continuous development, you have good chances to narrow down the culprit by bisecting. The assumption is, one single SVN commit broke your functionality and you just have to find out which one. Get sources from SVN, then switch to the earliest Stable/7 to confirm your assumption ("it broke with 7"). If it works, check out a few thousand SVN revisions later, try again. If it doesn't work, switch to an earlier revision, a late Stable/6. Each step cuts the number of SVN revisions in question in half, after some 10 or 12 iterations you're down to a single revision. Having a single revision pretty much directly points you to what the problem is. This helps developers very much and with some luck you can reverse-apply this change to a more recent set of the sources. MarKus - - - - - - - - - - - - - - - - - - - Dipl. Ing.
