I have higher power consumption after suspend-resume. It raises from usual ~7 
Watts to 10-11 while idle (Measured by PowerTop). I'm using TLP powersaving 
utility on Ubuntu 18.04 LTS and Powertop as monitoring tool. Have not noticed 
any CPU frequency abnormalities. Also i've tried force set frequency limit by 
cpupower, but no result.
I found info that dGPU may power up after suspend-resume and cause high battery 
drain, but my system does not contain dGPU (2200u + vega 3 iGPU)

Still on factory 1.03 BIOS.
Also have random system hangs every 5-10 hours of runtime. Two times while 
gaming, and ambient sounds continue playing, but image freezes and system 
became totally unresponsible. idle=nomwait did not help. Now I've changed 
amdgpu firmware files and waiting for result... If problem will repeat, I'll 
check RAM and update bios.  

What is minimum CPU frequency for mobile Ryzens? I can't set less than 1600MHz 
with cpupower, but sometimes it falls to 1200 or so.
And none of methods (lscpu, cpupower frequency-info) shows turbo frequency 
capabilities - 2500 is maximum. But "cat /proc/cpuinfo" displays more than 
3000MHz while running Mozilla Kraken benchmark.

Title:
  Acer Aspire A315 IOAPIC failure on Ubuntu 18.04, kernel hangs, can't
  load, kernel freeze  (AMD Ryzen 5/Radeon/Raven) / AMDGPU Hybrid crash

Status in amd:

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:
  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.
