I have the same problem but I'm running Fedora 7 on our PowerEdge 2600. I have just updated from Fedora Core 2. It may work fine for some time but occasinally the clock is steped several minits, and in /var/log/messages the line "Feb 13 15:06:00 adara kernel: Clocksource tsc unstable (delta = 238990016277 ns)" is printed!
When this occurs the server hangs and none of the services running on the PowerEdge is available on the network (dhcp, bind, httpd, svn etc). The wierd thing is that I only have to activate the server from screen saver state and its back on the network again.
This is a very big problem because the backup to DLT-tapes also failes when this happens.
Please, someone help! I don't wont to go back to Fedora Core 2.
