Netgear Nighthawk R7800 Specific Setup

Add this to startup script:

Under System > Startup > Local Startup:

# -- fix occasional mystery reboots --
# Min scaling frequency: set to 800MHz because of L2 cache issues.
# Random reboots are related to switching the power states from lowest state.
# Bumping up the minimum frequency to 800MHz eliminated this issue completely.
echo 800000 > /sys/devices/system/cpu/cpufreq/policy0/scaling_min_freq
echo 800000 > /sys/devices/system/cpu/cpufreq/policy1/scaling_min_freq
