Carl Englund, the next step is to fully commit bisect from kernel 4.0.9
to 4.4 in order to identify the last good kernel commit, followed
immediately by the first bad one. This will allow for a more expedited
analysis of the root cause of your issue. Could you please do this
following https://wiki.ubuntu.com/Kernel/KernelBisection ?
Please note, finding adjacent kernel versions is not fully commit
bisecting.
Also, the kernel release names are irrelevant for the purposes of
bisecting.
It is most helpful that after the fix commit (not kernel version) has
been identified, you then mark this report Status Confirmed.
Thank you for your help.

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).
