Hi, 
Thank you Mr. Theodore

So, I tried this commands, and I get a big number of process! 

I observed that the kworker is not really the cause! the systemd-journal is
writing all times to the disk!, When I traced one of his used inodes, I found
it writing to /var/log/journal/****.journal, each time a file of 8MB.

It's notable that the debugging options:
    CONFIG_FUNCTION_TRACER
    CONFIG_FUNCTION_GRAPH_TRACER
    CONFIG_STACK_TRACER
    CONFIG_DYNAMIC_FTRACE

Are enabled in my working kernel (I installed it using the Arch repository)

Thanks!
