This seems like it can be closed, now that stap-prep is the documented
way to ensure all the debug packages are installed.

systemtap 2.1-1~experimental1 in debian now instructs users to see
README.Debian every time stap fails. README.Debian then asks them to run
the stap-prep command that installs all the required headers and
debugging symbols. This has been tested on both Debian and Ubuntu.

There is one, but it's very well hidden. (dont ask why, i dont know

Just an addition: There seems to be no linux-image-debug-generic package
in Intrepid. Will such a package be added later or should we be using
something else for Intrepid?

I have the same problem as OH mentioned in a

What packages contains the symbols for the loadable modules?

The package attached depends upon the mentioned required packages - give
it a go. I can't promise it won't break anything - but it would be nice
to have it tested. This package is for amd64.
** Attachment added: Revised systemtap package to resolve the issue about
dependencies
Can the systemtap package effectively do what is described in the
http://sourceware.org/systemtap/wiki/SystemtapOnUbuntu page?
$ sudo apt-get install linux-image-debug-generic
$ sudo ln -s /boot/vmlinux-debug-$(uname -r) /lib/modules/$(uname -r)/vmlinux
$ sudo apt-get install

Jordan,
This is still an issue in Hardy, are you still the correct person for
this to be assigned to?

I am unable to resolve module functions with systemtap, like:

I have linux-image-debug installed, but it only contains the _kernel_

Jordan, symlinking the debug kernel to the running kernel name doesn't
work for me. Am I doing something wrong? See bug 115830
Thanks

Miek, it is possible that this is a systemtap or kernel problem
(in which case we'd appreciate hearing more details about the
crash - see http://sourceware.org/systemtap/wiki/HowToReportBugs).
But it is also possible that your rebuilt kernel does not exactly
match the one you're *running*. This
Okay, I was typing this when systemtap decided to issue a illegal opcode
and crash my server :(
Anyhow. Looks like I got it working by:
apt-get install linux-source-2.6.20
compiling a kernel in /usr/src
setting /lib/modules/`uname -r`/build - /usr/src/linux-source-2.6.20
and then running
This is on powerpc - to get systemtap working I followed the instruction
from the previous post, but I still get errors:
./keyhack.stp -v

ms.

Hi Miek,
It may be possible that my instructions above are out of date. You need
the linux-image-debug-* package that matches your running kernel. You
can get your kernel version with running uname -a. As of now, I had to
install linux-image-debug-2.6.20-16-generic. Of course, the symlink name
I did all that, I've installed the debug-* package and fixed the
symlink - but still no go. I might try to run this on my AMD64 system.
But on power-pc it looks like a no-go.

Did you try with strace? What information did you get? You can also
