Subject[PATCH] new bug report script
Hi Alan,

could you please consider this patch for inclusion in your tree?

This is a patch against 2.4.0. It introduces a new bug reporting script
(scripts/bugreport.pl) that tries to simplify bug reporting for users. I
have also added a small hint to this script to REPORTING-BUGS.

To all: Please have a look at the script and give me your feedback so that
I can fix the errors and improve the script.

Kind regards,
Matthias

information they're really interested in. Don't feel you have to follow it.

+There are two possibilities:
+ a) use the new problem reporting script
+ b) collect the information and write the report by hand
+
+a) The problem reporting script resides under scripts/bugreport.pl
+Use it like this: "perl bugreport.pl filename", where filename is where the
+report is written to. This results (hopefully) in a usable problem report that
+you can add additional info to.
+
+b) First run the ver_linux script included as scripts/ver_linux or
at <URL:ftp://ftp.sai.msu.su/pub/Linux/ver_linux> It checks out
the version of some important subsystems. Run it with the command
"sh scripts/ver_linux"

+-This script needs testing. I have tested it on SuSE 7.0 (updated to 2.4.0)
+ and on Mandrake 6.1, so there might be small problems with other
+ distributions.
+-The script assumes that all called programs are in the path. If a program is
+ not found, 'not found' is printed in the problem report.
+-ksymoops uses the default parameters. If the kernel and the modules are
+ installed or compiled in different locations, there certainly are problems
+ with ksymoops. This is going to be fixed.
