Bug Description

I have found that kswapd0 is running at 100%. If i run ' echo 3 > /proc/sys/vm/drop_caches' the transfer of data improves but not to initial levels. If that is not done more than a few times the system eventually grinds to a halt and reboot is required. The file transfer is usually between external usb drives. Beginning of xfer speeds are usually 17 - 20 mbit but will slow to less than 1mbit. This hasn't previously been a problem but i have tried rebooting with 3 or 4 older kernels and same problem exists. Older kernels wont start for some reason ! That timing coincides with a new graphics board i installed. Not relevant to the issue but may explain earlier than .30 kernels not allowing me to login ! As it is the system is unusable for any major file transfers. I have been patching all relevant patches on to my system which is running 16.10

During file transfer kswapd0 starts using CPU a lot. This happens on 4.8 kernel but not on 4.4.

This is an unsupported release now. Please think to install the next LTS 'Bionic 18.04'

Changed in nautilus (Ubuntu):
status: Confirmed → Invalid

Marking as Invalid because the release is EOL is not correct. Marking as Incomplete. Also, 18.04 is (at the time of writing) still in development, and you should expect some breakage.

Reporter, is this still present on 17.10 or 16.04?
