Re: cpufreq longhaul locks up

Would be good to check if PLL really can go downto x4,0. Can You
limit minimal CPU multiplier to 5,0 and check if is stable? If it
is check 4,5.

I directly wrote to /sys/devices/system/cpu/cpu0/cpufreq, which
worked better than `cpufreq -u xxx -d xxx`.

Lockup after 9 minutes. (Perhaps the longest time so far.)
[ this was with powersave compiled in and default]

Can You send me Your entire boot log with performance governor set?

This is the default kernel with performance gov:
