Title:
  System slow unless using touchpad

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  I tested this installing the Disks tool and running a read-only
  benchmark. The transfer rate is very slow (2-3 MB/s) unless I'm moving
  the cursor, then it jumps up.

  As I understand this could have something to do with
  triggering/handling interrupts. In this context it might be relevant
  to know that installing and running Xenial, I now need to have nolapic
  or noapic (or both) for the system to work at all. This is not the
  case with Trusty (also installed on this machine).
