After few inactive sessions today, I haven’t experienced any freezes. I want to wait until tomorrow for further testing until I mark it as solved, but as it seems to me the BIOS update seems to have fixed my issue.
For those who are interested, then the error I notice is this one
tpm tpm0: AMD fTPM version 0x3004900000005 causes system stutter; hwrng disabled linux
And the solution I found by googling this issue
