pessoal, 
 
estou tendo algums problemas com uma placa intel se7502hg2 e gostaria 
de saber se alguem pode dar alguma ajuda. 
 
sintoma:  
quando eh habilitada a opcao PAE no kernel do FreeBSD, durante a  
deteccao de dispositivos, ocorre um erro GPF (General Protection Fault), o  
boot do sistema e interrompido e o hadware trava, sendo necessario o  
desligamento fisico do equipamento.  
quanto a opcao acpi eh habilitada conjuntamente com PAE, o software  
nao consegue sequer iniciar a deteccao de dispositivos, parando logo 
apos a mensagem de copyright. 
 
solucoes adotadas:  
verificando a documentacao do FreeBSD, encontrei algumas referencias a  
incompatibilidades entre a controladora SCSI on-board e PAE (/usr/src/
sys/i386/conf/PAE).  
exclui os modulos do kernel, desativei o dispositivo via setup, instalei uma  
outra controladora (adaptec 29160 - ahc), recompilei, reinstalei e reiniciei 
a maquina.  
o problema persiste. 
 
software:   
FreeBSD 5.2-Release#0
