I've been doing some reading around
pcie_port_pm (after AMD issue *atombios stuck in loop for 5 sec* SOLUTION) and came across this on GitHub:
It's a list of GRUB option workarounds for newer hybrid Nvidia laptops. There's one common item:
acpi_os=! acpi_osi="Windows 2009"
that might be worth testing.
I'm not sure if it's possible to pass this as an option specifically when selecting an item in the GRUB boot menu (for the installer images), but if so, and it doesn't break older laptops, it might be worth trying out.
I'm about to test it on my hybrid now (which already works correctly).
No apparent negative effects on my i7-3630QM + GTX680M.
Anyone else for some testing?
