Hi folks I have spent some time recently looking through the results of various G***le searches relating to LI and Leap Second and other related matters and cannot find an answer to the below. I would appreciate help since we need to cover the scenario where our 2.6.9 Linux kernel may crash/hang when a leap Second insert occurs (due to the printk bug).
Some context to avoid repetitive simple answers along lines of upgrade XYZ: * we cannot move to the later 2.6.29 kernel for commercial reasons * we have an old NTP implementation: ntpd: ntpd 4.2.0a@1.1190-r Mon Oct 11 09:10:20 EDT 2004 (1) and again we cannot upgrade this -- certainly in the timeframe prior to June 2012. In view of the above, my question(s) are: + is there a way to disable the kernel from implementing the leap second from a prior announcement? (I.e. during June the NTPD receives a LI notification and tells kernel -- my reading of various posts and RFC/protocol suggests that this can occur anytime in June and specifically in the 24 hours prior to leap second implementation) + will stopping NTPD temporarily for a few days around the end of June avoid having the leap second implemented? (Re-enabling NTPD post the 30 June should re-synchronise time after some interval, correct?) These two questions are related to a potential strategy for covering the leap second hiatus.
