Just installed 14.04.2 64-bit, same note (Acer e5-551). Same error.

dw_dmac INTL9C60:00: invalid resource

"SCI (ACPI GSI 9) not registered" and
"i2c_designware 80860F41:02 failure requesting irq 34"
"i2c_designware 80860F41:05 failure requesting irq 37"

i2c errors disappeared after I disabled Advanced mode of touchpad (it was something about it uses I2C so better to be disabled on most of systems).

And dw_dmac error disappeared after I set

modprobe.blacklist=dw_dmac,dw_dmac_core

during boot. I can installed system, though touchpad worked strange (constantly pressing buttons).

After install and upgrade system booted. It was same dw_dmac error, but system booted. It is late, so i'll try to investigate something tomorrow. What info should I provide?
