Bug#425728: linux-image-2.6.20-1-686: kernel is failing to keep system time
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 16:39:09 ntpdate[18204]: step time server 193.68.149.1 offset -7447.277012 sec
23 May 18:02:32 ntpdate[18287]: step time server 195.22.25.130 offset -2434.564142 sec
23 May 18:29:48 ntpdate[18318]: step time server 212.13.194.96 offset -802.472908 sec
23 May 18:38:35 ntpdate[18336]: step time server 212.13.194.96 offset -273.594239 sec
23 May 18:41:36 ntpdate[18354]: step time server 212.101.3.211 offset -91.256144 sec
23 May 18:42:34 ntpdate[18362]: step time server 212.101.3.211 offset -34.457180 sec
23 May 18:42:54 ntpdate[18366]: step time server 193.218.127.251 offset -13.484830 sec
23 May 18:43:01 ntpdate[18370]: step time server 212.101.3.211 offset -8.033530 sec
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.
