kernel 3.13-61/62 /cpu1/cpufreq/stats

[Ludwig Petrosyan]

Hello

we have problem boot kernel 3.13-61/62 on the MTCA crate, some time it
boots some time no.
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
