ProxMox Freezing On AMD RYZEN Machines

[guletz]

Hi,

I have test 2 variants, and the both was succefuly for me:

1) only with "processor.max_cstate=1" => SUCCESS
2) "rcu_nocbs=0-11 processor.max_cstate=1" => SUCCESS

Also with HT on/off(BIOS) and with 1) and 2) all combination => SUCCESS


Good Luck!

Thanks! - Is rcu_nocbs=0-15 the only required parameter or is the parameter processor.max_cstate=1 also needed?

Only processor.max_cstate=1 but I think this also depends by your MB. In my case, I have upgrade my MB bios to be sure.
