Can confirm that issuing a full set of reads on all cores (0-47 in my
case) successfully unwedged the display. The display continues to update
properly some 16 hours later, though no reboot has occurred.
for i in $(seq 0 47)
do cat /sys/devices/system/cpu/cpu${i}/cpufreq/scaling_cur_freq
done
I had attempted to just repeatedly read the entry for cpu1 and that did
not have the desired effect.
