htop и sytem-monitor показывают 0 cpu ubuntu 20.04 ryzen 3950x

Я только что собрал новый компьютер и сделал двойную загрузку с Ubuntu 20.04. У меня проблемы с ryzen 3950x, htop и системный монитор не распознают процессор (вместо 32 показывает 1 поток). Я должен запустить его с acpi = off, потому что ubuntu не запускается. Это проблема с совместимостью? Мой BIOS был обновлен во время сборки компьютера (3 недели назад,B550 AORUS ELITE AX V2 (ред. 1.0)) Можете ли вы помочь мне с неправильным количеством потоков в htop / системном мониторе

Я запутался
