BETA edition rcu errors

[8bit]

Setting the max frequency to the minimum frequency eliminates almost all the errors.

Code:

echo 648000 > /sys/devices/system/cpu/cpufreq/policy0/scaling_max_freq

This seems to only work reliably are 648MHz. I tried setting min/max to 816MHz and the errors returned, though it seems less then if allowing the full frequency range.

Code:

echo 816000 > /sys/devices/system/cpu/cpufreq/policy0/scaling_max_freq
echo 816000 > /sys/devices/system/cpu/cpufreq/policy0/scaling_min_freq
