Thank you Jason - you have saved the day for a Linux ignoramus. I am downloading the source RPM as we speak (err...type), and will dig through it as soon as it is installed.
I cannot guarantee that all my fishing endeavors will be a success now, but I should at least be able to come up with a good fish story ;-).

First, I googled for your terms "linux kernel parameters proc printk", which led me to this post: http://www.ussg.iu.edu/hypermail/linux/kernel/0304.1/0922.html I noticed that the diff refers back to the Documentation directory under the kernel source. Doing a recursive grep for some of those terms (particularly printk) and piping it through your pager will reveal some good sources. When I ran across "The four values in printk denote", I knew I'd struck gold. Hope this helps your future fishing endeavors. ;-) -- Jason Dixon, RHCE DixonGroup Consulting http://www.dixongroup.net -- redhat-list mailing list unsubscribe mailto:[EMAIL PROTECTED] https://www.redhat.com/mailman/listinfo/redhat-list -- redhat-list mailing list unsubscribe mailto:[EMAIL PROTECTED] https://www.redhat.com/mailman/listinfo/redhat-list
