One can run the date call even while ntpd keeps running. >TODOs: >* Chase down the futex/hrtimer interaction to see if this could >be triggered in any other way. >* Get Tglx's input/ack >* Generate a backport for pre-v3.4 kernels It looks like 2.6.37.6 is not affected (on a system where ntpd is running). That is to say, at least the mysqld instance on such a system did not jump to high CPU usage. I did not try your testcase.c there, since that would likely freak out the webapps - or the management. Other reports on IRC include that 2.6.32-71.el6 (RHEL) is affected.
