I have done repeated installs of 14.04 LTS and 15.04 on an HP Stream 11
notebooks.

This issue generally does NOT occur, other than briefly during initial
load of Ubuntu installer (and sometimes during early stages of install).
This adds no more than 15% to the time it takes to install Ubuntu (with
eMMC storage), and will usually take less than 30 minutes.

However, I realised recently that this was ONLY true for new machines,
or those I had already installed Ubuntu on. Out of the box, I was
interrupting initial startup (at screen backlight on) to go directly to
(BIOS controls for) booting from USB device.

For machines that had were already running Windows 8.1 (or even just
asking for region / user details), it will no longer cleanly install
Ubuntu. I have had it take from 2 hours to 5-7 hours, or just stall
(after about 40 minutes) with continuous errors. This appears to be
spurious interrupts (which cause further errors) due to attempts to
access the RPMB partition. I am NOT even convinced that the Ubuntu
installer is causing these interrupts.

The other possible 'root cause' is that the problem machines (NEW or
used) were older, the same model Notebook but with an earlier generation
/ step release of eMMC chips. I don't have a large enough pool to prove
this, but someone may be able to shed light.
