Description Oscar Andrea Merandi 2017-01-02 18:09:03 UTC
I use gentoo (hardened profile) with hardened kernel.

polkit uses a lot of cpu with hardened kernel, with non-hardened kernel no problem.

I confirm. When I got 100% cpu I just do "killall -HUP polkitd" to restart it.
I have no idea how to force this bug...
Can say I went with version down in gentoo packages but it's happening again and again... so this is not only one relase bug.
