Hello. New to the forum, but I've been using Linux for over a year now. I've had a recent problem that generated lots of errors in the syslog, messages, and kernel log files. Since they're in all three, I am assuming that they are kernel error messages. I am having a hard time understanding how to interpret the error messages. I'm not looking for someone to solve my problem, only how do I read and interpret these messages. Sorry in advance if this is not in the right area of the forum. I'm running 64studio with kernel 2.6.19-rt12

Here's a sample from the kernel log:

For esoteric topics like that you really should visit the http://kerneltrap.org/ FAQ pages and forums. That's the place for finding guys who can fluently read kernelese.

Thanks. I check it out.
