Yeah strange things. I think those are older rare indirect outcoming of bugs. Just now it happens more frequently. There is a deep bug related to charging and kernel which seem to be here since kp49, but until the update to kp51 only 2-4 occurences were catched, including older mine with borked video player when battery were near to entry (reboot and charge up cured the bug temporary then). It seems one of these bug which are conditional bomb (happens only when specific conditions happens, I refer to bug/worm behaviour, not the real bomb). I guess latest CSSU update make such condition much more common AND the bug worsened in kp51. Please remind me proper powertop to file comand because I want to post it here for pali or freemangordon checking if it is good or problem (I'm not that good at reading powertop so I have to post it whole and hope to copy-paste). I have problem at isolating my problem to single cause (there can be at least two causes at once and I'm bad at not doing something coindeincialy).
