SuSE 9.0 large clock drift

Hi, I have a Dell 2650 that I recently converted from RedHat to SuSE 9.0 and since the conversion I am seeing large clock drift. I'm using this machine as a local ntp server so this is a real problem. Ntp resets the clock about every half hour when it has drifted far enough from the remote time server. Anyone else see this with SuSE 9.0? Any suggestions? -- ------- Stephan
