I have also been confused about System.map and using more that one kernel. The following url has a write-up about it, but it is not very clear about how to use a System.map that matches which kernel!!! http://www.linuxmafia.com/~rick/linux-info/systemmap.html The url does point out that the System.map is not important when it comes to the kernel running or not. System.map is used by klogd after a kernel oops for debug purposes. Also the url points out that other programs use the System.map and it gives some examples of these programs. The url also points out how klogd finds the System.map. Peter[no last name given] -the author of this article- knows of no way to resolve this conflict of matching the right System.map to the correct kernel!!!??? I can only suggest writing a script that is executed after the system is booted that checks which kernel has booted and then changing the syslink of System.map to match. 'uname -r' will list the kernel version. Maybe something from here could be used in the script. Maybe I will look into this further tomorrow?? At least this is a start at explaining the usage of System.map. HTH Charles
