Image of System Monitor

Is there any solution to this ?
Same happens with Linux kernel 4.1.6

I have noticed that when I use my Android via USB, the kworker starts consuming 15% cpu. Stats shows 15% but actually the map in System monitor shows 100% graph in one CPU.

Re: Kworker & Ksoftirqd Using 15% and 10% of CPU Respectively.

same, no fix i've found is a fix

went to 'testing' yesterday and had the same error as you said

something with the usb_core

we wait
