Carl Englund:
1) Please provide the output of the following terminal command (not perform an
apport-collect):
sudo dmidecode -s bios-version && sudo dmidecode -s bios-
2) Regarding having to use kernel parameters noapic and nolapic, the
issue of the system slow using the touchpad would be correlated with you
now having to use these parameters to boot since upgrading from Trusty.
Hence, let this report be rescoped why how you have to boot with
noapic/nolapic.
3) Could you please advise to what was the last kernel version you were
using that didn't cause this problem?

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).
