logging boot messages

[juggle]

Hi I get an error message when linux boots (I believe it's about some module) but cannot read it because it goes away too quickly. Now I tried to find it in any of my logs but it's not there. I tried demsg, I also put a rule *.* in the syslog.conf file but the error message is not in those log files. Does anyone know of a way to log these messages?

regards, Stefan

You could try hitting the pause button on your keyboard when the error displays, but im not too sure if that would pause the output or not.

Hello,

dmesg should log the error message that appears while booting. Please try to note one or two words in the error messages and suppose kernel is the word that is present in the error. Then type this command.

dmesg | grep kernel

Here the output of the command dmesg will be searched for the word "kernel", by the grep command.
