As per the kernel message, attached is the output of dmidecode for this
machine.
Adding acpi_osi=!Linux causes this to be logged:
ACPI: Disabled _OSI(Linux)
(at least I think it does; I don't remember seeing it before)
I'm not sure what other effects, if any, this is supposed to have?
The ACPI driver also complains on boot:
ACPI: BIOS bug: multiple APIC/MADT found, using 0
ACPI: If "acpi_apic_instance=2" works better, notify
[email protected]
This kernel option doesn't have any perceptible effect on anything other
than to say the same thing but to try to use acpi_apic_instance=0 :)
(IMO this laptop has more than its fair share of problems in Linux, or
Ubuntu at least; no particularly exotic hardware or anything. I don't
know how much ACPI-related stuff could be affecting this?)
Please don't hesitate to ask for any more information about this laptop!
Cheers, and happy holidays!
