We have some frequency stability issue in kernel release version 4.14.96, we have also created Frequency switching stability issues on Q820 thread previously. After applying changes suggested by @Loic in https://git.linaro.org/people/loic.poulain/linux.git/log/?h=qcomlt-4.14-820c-voltage-scaling branch, our cpufreq-bench issue got resolved but there is still a random boot failure issue.
We have tested kernel version 5.7.19 and it seems in this kernel version, random boot stuck issue got resolved (haven’t tested cpufreq-bench yet), we have tested approx. 70 hour reboot test and haven’t observed boot failure issue.
Now our condition is that we have released our product on 4.14.96 kernel and don’t want to upgrade whole kernel at this stage. So we want to know some path where we can port changes which solved this random boot failure issue. It will really helpful if we get to know specific patches or branch in which this issue was resolved.
