    The output from printk() appears in syslog only after a key is pressed on the system keyboard even though it is visible with dmesg immediately. There are patches for fixing this bug. What is the version of kernel installed on your server? You can find the same with the command,
    --
    uname -a
    --

    "The patch for this bug is by editing the vprink() function and make printk_recursion_bug_msg static and drop printk prefix from recursion variables and move them into vprintk()."

    The kernel in your server not the latest stable one and upgrading to the latest one should correct these bugs.

    It can be done by manually compiling kernel from source. The latest stable version is 2.6.30.1. You can get it from http://kernel.org
