Public bug reported:
After an update from 4.10.0-40-generic to 4.13.0-32-generic (ubuntu
16.04 + hwe kernel), the number of process when doing IO on my machine
has exploded.
Before the update, maximum number of process : 284
After the update, doing a simple rsync to an external disk : 771
The system is now unstable and crashes. The processes are hundreds of
"kworker".
Please let me know if there is something more needed.
