Red Hat Bugzilla – Bug 98273
(ISDN PCMCIA)system lockup upon stopping isdn
Last modified: 2007-04-18 12:55:23 EDT
Description of problem:
Restarting or stopping the service isdn locks system,
this happens in the running system but also upon
Version-Release number of selected component (if applicable):
redhat-network-config: 1.2.13-1 and 1.3.1-1
redhat-network-config-tui: 1.2.13-1 and 1.3.1-1
Steps to Reproduce:
1. /etc/rc.d/init.d/isdn stop
2. /etc/rc.d/init.d/isdn restart
3. Menu Services isdn stop
System lockup without error message, no error log entry
starting isdn causes no problems
for debugging, i need some infos:
which kernel version do you have on your machine?
which isdn card do you have?
please send to me your isdn config files
Thabnk you for the quick response. Here is the information you asked for:
uname -a on my machine outputs:
Linux my_pc_name 2.4.20-8 #1 i686 i686 i386 GNU/linux
I use an AVM Fritz PCMCIA isdn Card
The content of /etc/sysconfug/isdncard:
NAME='AVM Fritz Card PCMCIA'
There is no ifcfg-ippp0 in /etc/sysconfig/network-scripts, only
ifcfg-Tiscali (Tiscali is the name of my provider).
The contents of this file:
# Please read /usr/share/doc/initscripts-*/sysconfig.txt
# for the documentation of these parameters.
Perhaps the error has to do with the name of this file?
it looks like a problem in isdn driver. I assigned it to correct component
redhat-network-config 1.2.13-1 or 1.3.1-1 and
redhat-network-config-tui 1.2.13-1 or 1.3.1-1
redhat-network-config 1.2.0-2 and
eliminates the above problem.
Is it perhaps necessary for me to match the isdn4k-utils
(currently 3.1-62) to the redhat-network-config releases?
strange, redhat-config-network is only used for creating network config files.
It cannot cause such problem, because your config files look ok for me!
Are you sure that you only downgraded redhat-config-network? nothing else?
Have you reconfigured your isdn card with 1.2.0-2?
You are right, of course. I have repeated the up and downgrading of the
redaht-network-config packets, and now the lock up problem prevailes.
Also, stopping the pcmcia service causes a lockup
The removal of isdn4k-utils also causes a lock up.
A forced installation of isdn4k-utils works but changes nothing
The problem seems to be at the stage of loading the isdn-module
during boot, which fails.
After all this, I should congratulate you to the journaling file system!
I will continue to try to find the cause, perhaps you have a tip or two?
Installation of Shrike 9A has resolved the problems
