ISDN Driver Cannot Be Unloaded During Shutdown

Support knowledgebase (jbartsh_isdn_shutdown_failure)
Applies to

SuSE Linux: Version 7.3

Symptom

During the system shutdown, the ISDN driver cannot be unloaded. The system hangs.
The error message may look similar to this: unregister_netdevice: waiting for ippp0 to become free

Cause

An error in the by default installed Kernel 2.4.10

Solution

You can download an unofficial kernel update from our FTP server to fix this problem.
Please proceed as follows::

Log in as user root.

Check which kernel version you are currently using:

uname -r

rpm -qf `awk -F= '/image/{print $2}' < /etc/lilo.conf`

An output example:

tux# uname -r

2.4.10-4GB

tux# rpm -qf `awk -F= '/image/{print $2}' < /etc/lilo.conf`

k_deflt-2.4.10-23

Download the corresponding kernel from the following URL.

ftp://ftp.suse.com/pub/suse/i386/update/7.3/kernel/2.4.10/

Install the kernel with following commands:

rpm -Uhv k_XX.i386.rpm

mk_initrd

lilo 

(Obviously XX stands for the version you are using)

Finally, restart your computer.
