In my case ( see
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1460985 ) the
culprit generating huge I/O throughput was in /etc/cron.daily/man-db
It's such a long-standing and persistent bug that the default advice I
give nowadays to people complaining about their ubuntu "got stuck again"
4.2.0-17-generic #21-Ubuntu SMP x86_64 - the bug is still there with 15.10
I'm using asus ux31a btw.

Public bug reported:
This is trivial to reproduce - just plug any external drive with ntfs
and copy smth substantial to local ntfs partition. The result - mouse
doesn't even move most of the time, the system is useless and
unresponsive until copying is finished.
Yes, ntfs is not native on GNU/Lin

Hmm, scratch that - the failure reappears again even with this feature

Ok, I've managed to track this down to bios setting regarding "keep
feeding electrivity to usb ports while in sleep". So apparently this is
some quirk related to failed efi firmware or acpi tables for asus ux31a

No, I've got this issue for as long as I can remember.
Note: I've removed cron and installed systemd-cron instead but it didn't change
anything.
Next time I see this issue I'll try to check which processes started it.
If I'll figure out a way to trigger it reliably I'll check upstream
kernel too.
