Confirming this issue, Ryzen 2500U on HP Notebook 15-db0229ur.
- Disabling C-State C6 partially solves the problem
- Latest BIOS from manufacturer (F.11 Rev.A) - unable to access any of advanced settings!

Also bug here: https://bugzilla.redhat.com/show_bug.cgi?id=1562530

Disabling C6 states is not a fix it really. It's C6 idle state still, disabling it increases power consumption of CPU at least by 80% in idle state. This is certainly a kernel issue. Random freezes are random, they cause massive data loss as all you can do is to force reboot the laptop.

AMD did publish an errata report, pointing that this may be fixed at software level (page 63).
