@Ansuel @quarky @hnyman and all experienced users.
Currently my R7800 is running this @qosmio branch with NSS. I had two reboots for the first three days of use.
As there were opinions that the reboots were due to CPU frequency scaling issue I then switched to performance governor (without irqbalance and packet steering). Running for almost four days and still no reboot.
Currently @ACwifidude 5.10 NSS master branch is running on 4 other R7800s without irqbalance and packet steering but with the default ondemand CPU optimized settings.
echo 600000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq
echo 600000 > /sys/devices/system/cpu/cpu1/cpufreq/scaling_min_freq
echo 25 > /sys/devices/system/cpu/cpufreq/ondemand/up_threshold
echo 10 > /sys/devices/system/cpu/cpufreq/ondemand/sampling_down_factor
They all are free from any spontaneous reboots for more than 15 days.
Now first of all excuse my lack of competence on the subject and the great appreciation to all that work on this but I really wonder.
How could something so fundamental as CPU scaling, present on a vast majority of hardware and software (Linux, Windows, Android, iOS and others) for a long time, cause such an issue.
