Since todays kernel update (3.13.0-46.76 -> 3.13.0-46.77) I also see this message in my kern.log It has not been there before and I'm just wondering what will happen if this continues as the "too long" value seems to be continiously rising and the sample rate is being lowered

Also another problem is that IPv6 is not working any more during bootup after todays kernel update thus nginx can not bind to the IPv6 address given in the configuration and refuses to start up. Kernels should be tested more before releasing these updates... -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1246216 Title: perf samples too long (2519 > 2500), lowering kernel.perf_event_max_sample_rate to 50000 Status in linux package in Ubuntu: Invalid Bug description: This message appears in dmesg after a while every time system is booted up.
