This is the standard "weird hangs" answer, forgive me if you've already checked these: 1) Does is hang on other hardware as well or just this machine? 2) Have you checked the RAM with memtest86 or similar? 3) Have you ensured the hardware isn't overheating? 4) Is the box in question on a UPS? These seem to be the most common problems with FreeBSD hanging. I know none of them have much to do with FreeBSD, but that's just the statistical reality of it. If the answer to #1 indicates an issue with this particular machine, it could still be a problem with FreeBSD on that particular hardware. #4 is a rarity, but I've seen crappy power cause weird problems. Undersized power supplies can cause similar problems. -- Bill Moran Potential Technologies http://www.potentialtech.com
