Hope anyone has an idea... Everything changes so much because this is a hardware problem, thus it affects just about everything on your system. There's a FAQ entry on this, but I just noticed that it's woefully out of date. First off, 5.0-RELEASE is pretty old and has a number of known problems with it. You'll have better luck all around if you install 5.2.1. It's possible that this is a bug in 5.0 that's since been fixed, so I would first install 5.2.1 and see if the problem goes away. If it doesn't then the problem is hardware related. The explanation is that your computer hardware actually has multiple clocks in it. The kernel has to pick a particular clock for scheduling the operating the system when it boots up, and the clock it chose on your system is apparently inaccurate as hell ... to the point that it actually ticks backwards sometimes. The trick is to find out what other clocks are available on your motherboard and tell the kernel to use a different one until you find one that ticks accurately. Believe it or not, the FAQ entry for this other problem is pretty much the same solution you can use to fix yours: http://www.freebsd.org/doc/en_US.ISO8859-1/books/faq/troubleshoot.html#LAPTOP-CLOCK-SKEW -- Bill Moran Potential Technologies http://www.potentialtech.com
