I've successfully installed Linux Mint 17.2 MATE 64 on my Acer Aspire E5-511 laptop for dualboot with OEM Windows 8.1 Home 64 SL (which works fine except dropping wifi after de-hibernation).
The installation media is a 4GB flash stick; burned with Rufus.
I had to play with kernel commandline to boot the liveUSB; probed acpi_backlight='vendor' and nodma. At some point it managed to get past the line

dw_dmac INTL9C60:00: invalid resource
(now without fan spinning crazy each 20sec or so)

ubuntu/grub-efi-x64 added to UEFI, but not present in UEFI boot priority settings. Never ever tried to switch to Legacy mode.
However, to get freshly installed system up and running, I needed to write something into kernel commandline again.
acpi_backlight='vendor' -- doesn't fix it.
nodma -- ? Needs testing
Nothing interesting in $dmesg|less.

Cannot poweroff, OS halts (stops responding) and CPU fan starts spinning in squarewave pattern each 20sec so I hold the power button to switch it all off.

Does disabling DMA affect performance or battery life?

btw, on first successful boot into installed system touchpad didn't work. UEFI setting 'Touchpad mode Advanced/Basic' didn't seem to change anything.

I am happy to hand any logs or hardware info at your request.
