Collection of outputs from X555U laptop

Good day.
I have updated this laptop to the latest vendor supplied BIOS 204 10/18/2015.

Attempted distribution: Ubuntu mate 15.10.
Had to use acpi=off boot parameter to install linux
Eventually found more hardware worked with the pci=nommconf boot parameter

With pci=nommconf the following still does not work:
- Realtec rtl8821ae 802.11ac wireless NIC PCIe will only run in 2.4GHz mode. 5GHz mode will not work.
- Laptop will not resume after suspend

Many boot errors show in dmesg:
ACPI: AE_NOT_FOUND errors
systemd: failed to insert module 'kdbus' function not implemented

If pci=nommconf not used as boot parameter there is a looping pci-e error message that I cant break out of. From what I can read it says:
printk messages dropped pcieport 0000:00:... id=00E5(Receiver ID)

In the attached file is the following when pci=nommconf boot parameter used:
sudo output of:
dmesg
uname -a
lspci -vvnn
dmidecode
Tarball of /proc/acpi directory

Note: I am unable to resume from hibernate everything is frozen. So I am not able to attach a copy of /var/log/kern.log.0
