[Bug 1644249] Re: Ubuntu 16.04.1 installer crash

[Jorgeluis Guerra]

The PCI express error is not related and was not because the motherboard was faulty, it is a bug related to the Skylake CPU series.
I applied the workaround described here:

I understand and already did what you suggested, but i thought that the
installer should have not crashed because of it.
