[FUG-BR] Free 6.1 resetando sozinho, sera hardware ?

[Tempra Turbo]

Tenho um dell power edge 1800 com 2 cpu com HT habilitado 4G de ram e raid 5 SCSI
controladora perc.

O freebsd é o 6.1 release.

O que acontece é que volta e meia reseta sozinho, nao consegui achar nenhuma pista
em lugar algum do motivo do reset. Alguem sabe se tem algum arquivo de log onde olhar ?
ou o que fazer para ver se o motivo é software ou hardware ?

estou enviando abaixo meu kernel e o sysctl
