Greetings! New laptop and suffers a few ACPI issues on linux.

OS: Ubuntu 14.10 64bit

Current kernel: 3.17.0-031700-generic #201410060605 SMP Mon Oct 6 10:07:09 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux (from ubuntu mainline) (also running ubuntu 14.10's latest default based on 3.16.3 ("3.16.0.21.22")

Laptop: Acer Aspire E5-511, with latest BIOS (v1.03)

result of 'sudo acpidump'

Booting is very temperamental, and i can't get it to hibernate/suspend without becoming totally non-responsive to get the /var/log/kern.log.0 file.
However, these are the results of debugging boot parameters:

acpi=off boots but with fans constantly going
acpi=ht boots, fan behaves itself
pci=noacpi doesn't boot, hangs on garbled text
acpi=noirq boots but then hangs on plymouth splash
pnpacpi=off boots and behaves itself reasonably (currently using this)
noapic xor nolapic neither boot

/proc/acpi/fan and /proc/acpi/thermal_zone/*/trip_points via 'cat' are both empty.

Recurring error messages printed:
dw_dmac INTL9C60:00: invalid resource (for anything with the power button?)

and the following with the latter acpi debugging parameters:
"SCI (ACPI GSI 9) not registered" and
"i2c_designware 80860F41:02 failure requesting irq 34"
"i2c_designware 80860F41:05 failure requesting irq 37"
