Just tried to run `powertop` (after Linux 5.2 upgrade, but not sure if it worked for me before, ever used it): ``` $ sudo powertop modprobe cpufreq_stats failedCannot load from file /var/cache/powertop/saved_results.powertop Cannot load from file /var/cache/powertop/saved_parameters.powertop File will be loaded after taking minimum number of measurement(s) with battery only RAPL device for cpu 0 RAPL Using PowerCap Sysfs : Domain Mask f RAPL device for cpu 0 RAPL Using PowerCap Sysfs : Domain Mask f Nutraukta (killed) ``` Meanwhile, on kernel.log: ``` Aug 9 11:24:47 vinco kernel: [ 6493.332451] BUG: kernel NULL pointer dereference, address: 0000000000000000 Aug 9 11:24:47 vinco kernel: [ 6493.332455] #PF: supervisor instruction fetch in kernel mode Aug 9 11:24:47 vinco kernel: [ 6493.332456] #PF: error_code(0x0010) - not-present page Aug 9 11:24:47 vinco kernel: [ 6493.332458] PGD 0 P4D 0 Aug 9 11:24:47 vinco kernel: [ 6493.332460] Oops: 0010 [#12] SMP PTI Aug 9 11:24:47 vinco kernel: [ 6493.332463] CPU: 3 PID: 20189 Comm: powertop Tainted: G D OE 5.2.0-2-amd64 #1 Debian 5.2.7-1 Aug 9 11:24:47 vinco kernel: [ 6493.332464] Hardware name: ASUSTeK COMPUTER INC.
