Comment (by taos):
After comparing `ints` output before (see Ints_before.jpg) and after (see
Ints_after.jpg) the crash, I think the problem seems related to the
ipw2100 driver. The script is at the stage of installing the firmware for
ipw2100 when the crash occurs (see KDL+Terminal.jpg).
The following excerpt of [http://dev.haiku-
os.org/browser/haiku/trunk/data/bin/install-wifi-firmwares.sh install-
wifi-firmwares.sh] shows the more interesting parts relevant to the
installation of the ipw2100 firmware:
{{{
[...]
function UnlinkDriver()
{
# remove the driver's symlink
rm -f "${driversDir}/dev/net/${driver}"
}
function SymlinkDriver()
{
# restore the driver's symlink
cd "${driversDir}/dev/net/"
ln -sf "../../bin/${driver}" "${driver}"
}
[...]
function SetFirmwarePermissions()
{
cd ${firmwareDir}/${driver}/
for file in * ; do
if [ "$file" != "$driver" ] ; then
chmod a=r $file
fi
done
}
[...]
function PreFirmwareInstallation()
{
echo "Installing firmware for ${driver} ..."
mkdir -p "${firmwareDir}/${driver}"
UnlinkDriver
}
function PostFirmwareInstallation()
{
SetFirmwarePermissions
SymlinkDriver
CleanTemporaryFiles
echo "... firmware for ${driver} has been installed."
}
function InstallIpw2100()
{
driver='ipw2100'
PreFirmwareInstallation
# Extract contents.
local file='ipw2100-fw-1.3.tgz'
# In case the file doesn's exist.
if [ ! -e ${firmwareDir}/${driver}/$file ] ; then
url='http://ipw2100.sourceforge.net/firmware.php?fid=4'
OpenIntelFirmwareWebpage $url $file
fi
# TODO: handle when $file hasn't been saved in
${firmwareDir}/${driver}/
# Install the firmware & license file by extracting in place.
cd "${firmwareDir}/${driver}"
gunzip < "$file" | tar xf -
PostFirmwareInstallation
}
}}}
As I can't find any extracted firmware files I suppose the crash happened
during the first step "PreFirmwareInstallation".
