Todas as vezes que ligo ou reinicio o meu notebook (sistema Linux Mint), aparecem os erros a seguir:

pci 0000 :00 :00.2: AMD-Vi: Unable to read/write to IOMMU perf counter.
integrity: Problem loading X.509 certificate -65

Após esse erro, aparece a logo verde do Linux Mint e depois a tela escurece, surgindo em seguida novamente o erro já mencionado. Posteriormente, fica com a seguinte tela:
Linux Mint 20 Ulyana user tty1
user login:

Após essa mensagem o visor escurece e segue para a tela de bloqueio. Quando não, simplesmente o visor fica escuro, a tela de bloqueio não aparece e o notebook para de responder, sendo preciso assim forçar o desligamento pressionando a tecla Power. Depois desse processo o sistema inicia normalmente surgindo apenas o erro: integrity: Problem loading X.509 certificate -65

A saída para inxi -Fxz
