siyia: I see you only have rcu_nocbs=0-3 but there are 8 logical cores. Try seeing if using `rcu_nocbs=0-7 idle=nomwait` helps. Both those together fixed my system lockups. With just rcu_nocbs for all my cores I still got lockups (and you don't have it enabled for all cores). Ryzen Errata: https://support.amd.com/TechDocs/55449_Fam_17h_M_00h- 0Fh_Rev_Guide.pdf
