The patches applied well to my existing 6.2-PRE source tree (I did not cvsup so as to minimize the changes to the system and prove that this fix either does or does not work for my problem.) There was minimal line fuzz, but no failures. If this works out, I'll cvsup and re-patch and test the latest sources. I'm building and installing the kernel now. Tomorrow when I'm at the office I'll try the dump again as that usually causes a lockup. Thanks for helping me solve this. --Apple-Mail-3--916081353--
