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"
