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
