I honestly do not know what would be considered a good entropy bitrate..Sorry.
I still think it comes down to a timing issue or below.
Sat Jul 15 17:30:04 2017 kern.err kernel: [    1.276889] cpu cpu1: opp_list_debug_create_link: Failed to create link
Sat Jul 15 17:30:04 2017 kern.err kernel: [    1.283536] cpu cpu1: _add_opp_dev: Failed to register opp debugfs (-12)
I have been up from kernel bump to kernel bump for awhile now. No reboots for days at a time but when it happens it sure would be helpful to be able to grab a crash dump.
I do not know if the new GCC version has anything to do with it. Up time that is.

I do not even want to think about the hours I have spent to find out what the opp problem is.
It is beyond me.

Hopefully someone that knows what they are doing will get to the bottom of the issue.

I have also been using diizzyy's pull req. https://github.com/lede-project/source/pull/1211
