@siya, does this actually make the apic features work? I tried the latest fedora install (mate variation) from the website, as I don't really know much about kernels and so on.. Sure it ran without the errors after the initial installation, but it was still in the same state as ubuntu - hanging on suspend, extra keys not working, and even the touchpad was reduced to basic functionality, while in ubuntu it worked as advanced, even though it's set to "basic" in the BIOS. I didn't bother checking power drain and so on since if these are going to be broken anyways I'd rather use ubuntu..

Soft lockup Using pci=noacpi kernel parameter kernel loads without any problem but my notebook produces more heat than on Win10. If I know right Acer notebooks need ACPI to the correct power management. The same thing happens on mainline 4.17,4.18rc1-2. BIOS upgrade to the latest version: 1.08 hasn't helped This problem has been reported upstream: https://bugzilla.kernel.org/show_bug.cgi?id=200087 The latest correctly working kernel was 4.13.* but the heat problem was present with this too.
