After upgrading to Core Update 2.12, the graph containing the CPU frequencies ("cpufreq") is empty.
Created attachment 604 [details] CPU frequency graph
*** Bug 11739 has been marked as a duplicate of this bug. ***
I search for proper detecting cpufreq capability. On some systems /sys/devices/system/cpu/cpu/cpufreq/policy0/cpuinfo_cur_freq not exist and on Matthias system the whole /sys/devices/system/cpu/cpufreq/policy0 is missing. Please report if /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq exists on your system. (This is present on all machines that i have checked yet.)

Fixed in Core Update 123.
