  Acer Aspire A315 IOAPIC failure on Ubuntu 18.04, kernel hangs, can't

Bug description:
  CPU: Ryzen 5 2500U
  VGA: Radeon 535
  Notebook: Acer Aspire A315

  This is a brand new notebook on the market with Ryzen 5/Radeon.
  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:

  The latest correctly working kernel was 4.13.* but the heat problem
  was present with this too.
