Description of problem:
Waking up from standby
SELinux is preventing x86_energy_perf from 'read' accesses on the chr_file msr.

*****  Plugin device (91.4 confidence) suggests   ****************************

Wenn Sie erlauben wollen, dass x86_energy_perf  read Zugriff auf msr chr_file
Then sie müssen die Kennzeichnung von msr auf einen Typ eines ähnlichen Elementes ändern
Do
# semanage fcontext -a -t SIMILAR_TYPE 'msr'
# restorecon -v 'msr'

*****  Plugin catchall (9.59 confidence) suggests   **************************

If you believe that x86_energy_perf should be allowed read access on the msr chr_file by default.
Then sie sollten dies als Fehler melden.
Um diesen Zugriff zu erlauben, können Sie ein lokales Richtlinien-Modul erstellen.
Do
allow this access for now by executing:
# ausearch -c 'x86_energy_perf' --raw | audit2allow -M my-x86energyperf
# semodule -X 300 -i my-x86energyperf.pp

Description of problem:
Seems to happen when waking from sleep.  I suspect this might be triggered by package "tlp-rdw".

Description of problem:
I see this error from SELinux when my laptop (Lenovo ThinkPad X250) wakes up from hibernate. I hibernate the laptop by holding down the power button from 1-2 seconds.
