I've done some effort to get more information about the bug.

1. BIOS updates with the Lenovo tools are a bit confusing. I still stuck at the BIOS Version O3TKT46A from 07/21/2019. I've opened a support thread at https://forums.lenovo.com/t5/Lenovo-Desktop-Towers/V530-15ARR-Desktop-Tower-BIOS-update-confusion/td-p/4636769 .

2. I've recognized a difference in behavior since kernel 5.3.0-28-generic #30~18.04.1-Ubuntu: Wehn I put the computer into suspend it first does something like a kernel oops with
* RIP: 0010:irq_startup+0xe1/0x100
and after that it shows a few lines later
* PM: suspend_common(): xhci_pci_suspend+0x0/0xd0 returns -110
* PM: pci_pm_suspend(): hcd_pci_suspend+0x0/0x30 returns -110
* PM: dpm_run_callback(): pci_pm_suspend+0x0/0x150 returns -110
* PM: Device 0000:04:00.4 failed to suspend async: error -110
* PM: Some devices failed to suspend, or early wake event detected
then it follows endless repeating kernel oops with
* RIP: 0010:dcn10_verify_allow_pstate_change_high+0x37/0x2d0 [amdgpu]

I've attached the snippet of the journalctl output.
