I use syslog-ng as system logger. This kernel always logs messages with timestamp "[ 0.000000]" instead of actual time from the boot point. Reproducible: Always Steps to Reproduce: N/A Actual Results: See attachment Expected Results: It should print correct timestamp.

This issue seems to be specific to your hardware or config CONFIG_PRINTK_TIME seems to work fine elsewhere. Please post your kernel config. Also, would it be possible for you to try with gentoo-sources-2.6.24-r8?

Greetings to Gordon Malm (gengor), I am very sorry, but it is not possible for me to try gentoo-sources-2.6.24-r8 kernel, since this is mission-critical production server, and I prefer hardening features (PaX, GRsec, SElinux). Best, VooDooMan
Understandable regarding trying gentoo-sources. Did not know the role this machine plays in your operations, so it was worth asking. From what I can find this appears to be a regression in the mainline kernel and nothing to do with any of the hardened patchset (I never suspected it was related either). There are various patches floating around mainline git & LKML, but success at fixing the problem seems to be varied so I'm hesitant to backport them. I believe you should be able to work around the problem by enabling CONFIG_PM and CONFIG_ACPI in your kernel config. Enabling base ACPI support is a good idea on modern hardware anyway (even servers). Please let us know how it goes. Thank you.
Greetings Gordon, Here it is local time now 0703 hours. Notify of scheduled upgrade/reboot at approximatelly 1200 hours to the new kernel with your configuration changes suggestions have been sent to all users. I will get back here to report You whether it will work. Thank You very much, Marian. .
Greetings, I enabled power management per your suggestion, and now timestamps are printed correctly. Thank You very much, Marian .
Created attachment 162747 [details] kernel .config Greetings, If you are interested in kernel config that resolved an issue, there it is. Marian .
Greetings Gordon, Thank You for suggesting ACPI enabling. It resolved an issue with "/sbin/shutdown -h ..." and related "shutdown" things. This bug report IMO is only cosmetical bug, You are free to close it as fixed, however. Thank You very much, Marian. .

As for this bug, it is kernel@g.o's, not mine. So it is up to the Gentoo kernel team to decide what they want to do with it.
