Leaping seconds and looping servers
Posted Jul 7, 2012 1:36 UTC (Sat) by BenHutchings (subscriber, #37955)
The known bugs involving kernel hangs are:
1. Deadlock in printk at midnight (introduced in ???, fixed by commits b845b51, fa33507 in 2.6.29, 220.127.116.11, Debian package version 2.6.26-20)
2. Possible live-lock when NTP sets up the leap second (introduced in ???, fixed by 6b43ae8 in 3.4)
When I saw the fix for bug 2 it appeared that the live-lock being described was introduced by bd33126 etc. (post-3.3) and therefore not possible in earlier versions, but I'm no longer certain of this.
So I'm still hoping to find out what went wrong in 2.6.32 and in 3.2 so these can be fixed in stable updates.
