Any way to detect the problematical ram chips so the scaling_min_freq is a conditional setting based on the presense or absence of the chip?

And adding: echo 600000 > /sys/devices/system/cpu/cpufreq/policy0/scaling_min_freq echo ondemand > /sys/devices/system/cpu/cpufreq/policy0/scaling_governor to /etc/rc.local seems to fix the warm boot hang. -- Russell Senior [email protected]
