Hello! I've got a problem when I try to remove modules from kernel: in fact my operation system returns me a message of "segmentation fault" after rmmod name_module command?Why? Could anyone help me? Thank you very much! lucs

to get any more information you'd need to run the command inside of a debugger, i.e. gdb. when it crashes you can then use "bt" to print the backtrace of what was happening at the time it went down.

I've tried to use gdb but after compilation when I use gdb name_file and I type (gdb) run, it shows me this message:
This GDB was configured as "i386-slackware-linux"...
(gdb) run
Starting program: /direct1/direct2/direct3/name_file
/bin/bash: line 1: /direct1/direct2/direct3/name_file: Permission denied
/bin/bash: line 1: exec: /direct1/direct2/direct3/name_file: cannot execute: Success

Program exited with code 0176.
warning: shared library handler failed to enable breakpoint
You can't do that without a process to debug.

Maybe I don't understand what you want to say me, infact I'm not a very good kernel programmer, but where I have to put "bt" parameter?Thank you!
