Bug#679882: linux: leap second fixes missing in 3.2 and 2.6.32 longterm
Hi Ben, Is anything happening with this bug e.g. getting the patches into the Debian stable kernel package (2.6.32) and a new version pushed out? We had another meltdown at the end of August and it would be really helpful to have an upgrade before the end of this month (September, in 23 days). Nothing has been added to the bug report since the 5th of last month (August); if there is updated information could someone please update the bug report? Thanks/best, -- Steve Lane System Administrator, Scientific Computing Joint BioEnergy Institute Lawrence Berkeley National Laboratory -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".

But there have been reports of lockup in adjtimex() on earlier kernel versions, which might be a similar bug. > > media reports include > > http://www.heise.de/newsticker/meldung/Schaltsekunde-Linux-kann-einfrieren-1629683.html > > http://www.wired.com/wiredenterprise/2012/07/leap-second-bug-wreaks-havoc-with-java-linux/ > > > > newer patches include these to be watched: > http://thread.gmane.org/gmane.linux.kernel/1321255/ That's the one that caused user-space to effectively busy-wait.
