[Spacewalk-list] Python errors on rhnreg_ks

Fri Sep 3 13:34:05 UTC 2010

To all developers reading this I have discovered the route of the
problem but could probably do with some sort of workaround for others;

Basically as you know, when the system attaches itself to the server it
collects a load of  hardware information, this calls upon dmidecode
which scans /dev/mem.

The error although seemingly random seemed to happen on boxes that had a
loud of dodgy information in /dev/mem. I could get the servers
connecting to spacewalk by deleting the /dev/mem device (or renaming it
for the rhnreg_ks command and then rename it back).

I think there should be a workaround for this since this information was
nowhere on the internet. Should I raise a bug report since this was
happening to me 1 in 4 servers.

Cheers,

Chris

Hi all, I'm having an issue with spacewalk when I try and connect to the
server;

[root at lcmrst1 ~]# rhnreg_ks
--serverUrl=http://lcmspacewalk1.liquid-capital.liquidcap.com/XMLRPC
--activationkey=1-ac4909121ec738d6f8a4ac2842062d54

python: src/dmidecode.c:4083: dmi_decode: Assertion `sub_n != ((void
*)0)' failed.

Aborted

At first it was just a couple of boxes but after trying to deploy across
a range of boxes it has come up several times. I've googled to no avail,
I went on IRC and asked around and no one knew what the problem was so
I'm coming here.

I'm going to try and shoehorn a newer version of python-dmidecode
(possibly from fedora) but I wanted to come here to see why 7 out of 29
systems have this error, I'm happy to switch on debug mode, compare
install lists, anything to help you lot get to the bottom of this.

Some background info; all boxes installed identically off the same
kickstart script, on a wide range of off the shelf hardware, it fails
and works on 32bit/64bit centos 5.2 up to 5.5. A full yum upgrade
doesn't fix the problem and the version of python dmi-decode it installs
is 3.10.8-4.el5

Thank you all for your time,

Chris
