[FUG-BR] Pentium 4 HT Não reconhece segunda CPU

[Deleon Galvin]

Olá a todos!
Estou tendo um problema interessante. 
Verifico no ps ou no top q o FreeBSD reconhece os 2 CPU's lógicos, porém 
apenas um está trabalhando.
Olhando o DMESG eu verifiquei q realmente eh retornado um erro acpi_throttle1: 
failed to attach P_CNT e no final um erro SMP: AP CPU #1 Launched!

Por acaso mais alguem jah passou pelo problema?
Anteriormente eu tinha o HT desta maquina desabilitado, e após compilar o SMP 
e tentar reabilitar me deparei com o problema.
Abaixo segue parte do DMESG para identificação do hardware.

Fico no aguardo das opiniões dos caros colegas.

Um abraço!
