There's nothing worse, in doing troubleshooting, than making an assumption and going off into a blind alley for weeks, and trying to find a software problem in a system that's being overclocked is simply asking for it. Part of the price you pay for overclocking is needing to dial back the clock for any serious troubleshooting. Overclocking is basically unreliable; if it works, that's just fine, but the guarantee runs 60 seconds, max. The problem's real, but no trouble reports if you're overclocking, no excuses accepted. It's not all that hard to dial the clock back (and no, I don't overclock, myself, even though I do have a system that could do that well). ----------------------------+----------------------------------------------- Chuck Robey | Interests include any kind of voice or data chuckr@glue.umd.edu | communications topic, C programming, and Unix. 213 Lakeside Drive Apt T-1 | Greenbelt, MD 20770 | I run Journey2 and picnic (FreeBSD-current) (301) 220-2114 | and jaunt (NetBSD). ----------------------------+----------------------------------------------- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
