Dear Linux friends system clock in Red Hat Enterprise Linux 5 on my hp xw 9300 w/ Opteron runs approx 3x faster. In RHEL 3, RHEL 4 and Knoppix the clock runs O.K. Can I fix the problem or only RedHat can do this? In /sys/devices/system/clocksource/clocksource0 both available_clocksource and current_clocksource contain jiffies only. Also, what are the advantages of RHEL over fedora? Is it worth paying RHEL support if they do not accept a question like this one? Thanks for any help. -- Pavel Pokorny Math Dept, Prague Institute of Chemical Technology http://www.vscht.cz/mat/Pavel.Pokorny

Have you actually asked them? It sounds to me like it is aquestion they SHOULD answer under support.

This is complete nonesense. ntpd can keep a clock that is fast or slow by a few parts per million in line, but it CANNOT keep a clock that is 3x too fast in line. >> Also, what are the advantages of RHEL over fedora? >> Is it worth paying RHEL support if they do not >> accept a question like this one? >It would depend on what you were using your system for.

It is not a tax it is a support contract. The probability of fixing bugs in Fedora is I think actually higher than in RHEL. The former publishes the bugs publically. AFAIK, redhat delivers RHEL bug reports only to people who have a support contract, and that does not include the people who run Centos. >http://www.centos.org >This is RH srpms recompiled. The question is how well they keep up with the bug reports. I have not found a repository for the security update rpms. Maybe I have just not looked in the right place.
