Package: linux-image-2.6.20-1-686
Version: 2.6.20-3
Severity: important


Starting with the 2.6.18 kernel, I began to experience the following behaviour:

23 May 22:23:07 ntpdate[20795]: step time server 193.13.9.98 offset -8402.560620 sec

2.6.20 continues to be broken. A 2.6.17 kernel works just fine, no huge time displacements.

Version: 2.6.25-1

time subsys got heavily rewritten with nohz tickless kernels
and due too x86 arch merge.

very unlikely if that is not a hardware bug that it still exists.
