“lib/systemd/systemd-journald” using excessive amount of CPU
Yesterday I installed Ubuntu 16.04 LTS on my laptop, and I noticed that the process “lib/systemd/systemd-journald” is using 30-60% of my CPU. I don't know where the problem is. Can anyone please help?

Googling the AER error suggests it might be a bug in the kernel with certain (wifi) hardware. Workaround: add a boot parameter pci=noaer
