Answer 2

Eu sei qual é o problema, mas não a solução.

O Ubuntu tem uma versão desatualizada do Systemtap, o que significa que ele tenta compilar os cabeçalhos atuais do kernel. A função do kernel get_user_pages () foi alterada, mas o systemtap ainda está tentando usar a versão antiga.

Isso está causando erros de compilação. Eu não sei como consertar isso. O Ubuntu não atualizou seu pacote. A única solução em que consigo pensar é a compilação de uma versão mais nova do systemtap por conta própria ou comutação de distribuições.
