In the kernel log we found this problem: [ 16.168871] ------------[ cut here ]------------ [ 16.173513] WARNING: CPU: 0 PID: 4 at /build/linux-lts-trusty-G19QHO/linux-lts-trusty-3.13.0/fs/sysfs/dir.c:486 sysfs_warn_dup+0x91/0xb0() [ 16.185967] sysfs: cannot create duplicate filename '/devices/system/cpu/cpu1/cpufreq/stats' we found out thid peoblen is solved in the kernel 3.14 (file linux/drivers/cpufreq/cpufreq.c), is there some way to solve it for kernel 3.13-61/62 (some boot parameters ...) ? The older kernel 3.13-55 runs fine on the same CPU. with best regards Ludwig Petrosyan DESY
