The same installer runs without issue on other machines and the 16.04 installer runs without issue on the P650RE3. Without passing acpi=off and noapic, a desktop comes up and a terminal can be obtained, but keystrokes and mouse clicks are not responded to after a small number of seconds. The mouse pointer continues to move with trackpad input. With careful timing I was able to obtain, uname, dmidecode and (an empty) lspci output. I was not able to obtain any /proc/acpi information, but do have dmesg. These are all attached. With acpi=off and noapic, I can get lspci and dmidecode output, but obviously no /proc/acpi. In this case the lspci output is not impty and dmidecode is identical to the failing case.
