I don't know. I try to explain. With all debugging options
enabled 2.6.21.x has never crashed. After two days 2.6.21.3
was running without any debug options, it has crashed.
Tomorrow morning I will start that linux box with linux 2.6.21.3
without any debug options, and I will keep you informed
(friday evening I have switched back to 2.6.21.3 with debug
options enabled, so the machine doesn't crash during the week
end: this system is my company firewall.)
