[MASOCH-L] Ajuda com kernel panic

[Eduardo Schoedler]

Senhores,

Não sei se a lista MASOCH é para esse fim, se não for por favor me indiquem
uma lista melhor.

Estou com uma dificuldade no linux.
Não estou conseguindo descobrir por qual motivo está acontecendo um kernel
panic no linux.
É uma máquina Dell R900 com 16GB RAM, rodando dedicado para mysql.

Aparentemente parece ser um problema com o processo do mysqld... mas já
peguei o mesmo problema com o 'swapper'.

Alguma sugestão?
Onde consigo informações para interpretar esses kernel panic? Já procurei
mas não encontrei muita coisa.
