[Bug 1571564] [NEW] Unable to install Kubuntu 16.04

[Launchpad Bug Tracker]

I have downloaded Kubuntu 16.04 daily build 20160416 and created an
installation USB stick with USB Creator.

After booting from the stick the boot screen appears with alternatives:
Start Kubuntu, OEM installation and chck disc. I choose Start Kubuntu.

The Kubuntu logo flashes for a few seconds and then there is an awful
lot of Plasma chrashes. Some information is given in crash report
windows: "Executable: plasmashell PID:2109: Illegal instruction(4)".
The PID:s vary a lot: 2089, 2153, 2166, 2186, 1910 etc. It's not
possible to restart plasma or communicate in any other way with the
computer except closing the bug report windows. When done the screen is
just black with a mouse pointer (not frozen) but there seems to be no
way to continue or even bring forth a command shell. Hard reboot.

I have tested the same stick on two computers, both with UEFI, but with
different hardware. (Computer 1 Desktop: Intel Skylake 6500 Nvidia
graphic card, Computer 2: laptop Intel 5200U, Intel HD4400). Both fail.
I have downloaded the disc image several times and reformatted the
stick. I have booted from different USB ports, USB2 and USB3, and
nothing has worked. I have also tested the same stick with Ubuntu and
Xubuntu daily builds from the same day and they work without problems.

So it seems that the Kubuntu installer for 16.04 is broken. Other
flavours are unaffected.
