Hi all, I decided to try "ivrs_ioapic[4]=00:14.0 ivrs_ioapic[5]=0:00.2" and it actually worked for me. It is possible that I am a complete idiot and misspelled it 5 times in a row before, but I could have sworn it did nothing before. Now suspend and brightness keys work..:

The default kernel of Ubuntu(18.04) hangs at loading with message: tsc: Refined TSC clocksource calibration: 1996.250 MHz clocksource: tsc: mask: 0xffffffffffffffff max_cycles: (...), max_idle_ns: (...) 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.
