Strange problem with ps (System.map does not match kernel data)
I am running Debian/unstable, and the 2.4.4 kernel, patched with SGI xfs:
$ uname -a
Linux cbgb 2.4.4-xfs #1 Sun Jun 10 21:03:50 PDT 2001 i686 unknown
When I boot the system, everything is fine, but after a day or so,
whenever I run ps, I get the following error:
$ ps -ef
{shmem_file_setup} {__VERSIONED_SYMBOL(shmem_file_setup)}
Warning: /boot/System.map-2.4.4-xfs does not match kernel data.
UIDPID PPID C STIME TTY TIME CMD
root 1 0 0 Jul16 ?00:00:05 init
root 2 1 0 Jul16 ?00:00:00 [keventd]
... snip ...
This does not happen immediately; right after I boot, ps does not give
me the error message, but something happens at a later time and starts
causing problems.
Has anyone else seen this?

System.map does not match kernel data
hello
when i do `ps` , i get the following error message on stderr...
{inet_release} {inet_release_R__ver_inet_release}
Warning: /boot/System.map-2.4.2 does not match kernel data.
{inet_release} {inet_release_R__ver_inet_release}
Warning: /boot/System.map does not match kernel data.
{inet_release} {inet_release_R__ver_inet_release}
Warning: /usr/src/linux/System.map does not match kernel data.
what does it mean ? I *did* compile (and recompile ) my kernel a
dozen times..is it because of that ?
Thanks in advance..
regards
omicron

also sprach omicron (on Wed, 16 May 2001 03:57:53PM +0530): what does it mean ? I *did* compile (and recompile ) my kernel a dozen times..is it because of that ? yes. copy the file /usr/src/linux/System.map to /boot/System.map-`uname -r` and you are set. System.map maps kernel address space to function names such that proggies like ps, top, strace, and other debugging tools may present the user with meaningful names rather than 32/64bit addresses. martin; (greetings from the heart of the sun.) \ echo mailto: !#^.*|tr * mailto:; [EMAIL PROTECTED] -- the packages come out en masse, like minitab, systat, and sas. the ultimate mess is spss, which everyone uses, alas.
System.map does not match kernel data
Hi all, I'm getting the following message when I run ps/top: Warning: /boot/System.map-2.2.17 does not match kernel data. I'm assuming (hoping :-) that this is because I did a security update yesterday and something's not quite right. Any hints on what to do here?

Re: System.map does not match kernel data
Did you just upgrade your kernel? (I know 2.2.18pre21 or something just came out). I usually just make a symlink from /boot/System.map to /usr/src/linux/System.map. Then whenever I upgrade my kernel my System map stays consistent.

The message comes from a kernel symbol checking routine in (as far as i remember) misc/symbol.c in the ps source tree. I _knew_ for sure my symbols were correct, so i changed the '#if 1 --- #endif' that encloses exactly that statements to '#if 0'. not quite a fix but, guess what, no Warning message anymore 8:) greetings. martin

¡Hola! Pues eso, que cada vez que hago un 'ps' o un 'top', me sale el mensaje Warning: /usr/src/linux/System.map does not match kernel data. He recompilado e instalado el nuevo kernel, y he hecho lilo. ¿Que sucede con el System.map? ¿Como puedo volver a generarlo?

Jonas Is there some way of fixing this/get rid of the message? Yes there is. See below. Jonas I've compiled the kernel myself and the messages started to Jonas appear after (I think) and upgrade to PAM. Jonas (I have a foggy idea what this message means but don't know how Jonas to repair it.) The System.map is generated when a kernel is compiled. It can be found in the /usr/src/linux-x.y.z assuming that the kernel sources are in that directory. This file contains debugging symbol information that can be useful if and when the kernel crashes. If you are compiling the kernel by hand, then you need to copy the System.map from that directory into /boot right after the kernel has been compiled. I am not sure but it might have to be named with the kernel version ie /boot/System.map-2.2.12. Some of the make targets such as bzlilo automatically do that and setup /etc/lilo.conf. Someone will correct me if I am wrong here since I have been using the Debian's excellent kernel-package tools to build kernels and haven't done it the old-fashioned way. If you use the make-kpg script(s) to build the kernel in Debian, all this is taken care for you by the script(s). For more info on this, see : /usr/doc/kernel-package, and man make-kpkg.

I have the same problem, except my kernel was installed with kernel-package so I already have /boot/System.map-2.2.12 setup. Symlinking it to /boot/System.map just means I get two messages.
