Every time I look at the logs from
bootchart, I notice a process called
udevadm that is mostly coloured as if it is a zombie process. It is accompanied by
udevd. They take up about 25% of my computer's boot time and nothing seems to be happening during this time according to the graphs above the process chart.
It would be nice if someone gave an explanation of these processes, what they do, why
udevadm is a zombie most of the time and why nothing appears to be happening in the time they are running. If this is unnatural behaviour, I would also appreciate help on how to fix this.
