Public bug reported:
After update to Kernel 2.6.30-10-generic (AMD_64), I don't know what
package caused this - I guess something with udev - no wlan interfaces
are created.
I wrote some lines of code to make visible how it looks under the old Kernel
where the interfaces are still created and how it looks now:
here the code:
#!/bin/bash
wlandevice="Wireless WiFi Link 5100"
echo This shows the hal entries for \"$wlandevice\" device:
echo
echo -n "Used Kernel (uname -rvm): "
uname -rvm
echo
find_dev_id () {
pci_slot=`lspci -mm|grep -F \""$*"\"|sed -e "s/\( \)\{1\}.*$//"`
echo "`lspci -s $pci_slot -n|\
sed -e "s/^$pci_slot\( \)\{1\}\([0-9a-f]\)\{4\}:\( \)\{1\}/pci_/"\
-e "y/:/_/" -e "s/\( \)\{1\}(rev.*$//"`"
}
wlancard=/org/freedesktop/Hal/devices/`find_dev_id $wlandevice`
echo parent-device:
echo ==============
echo
lshal -u $wlancard
echo
echo \'child\'-devices:
echo ================
for udi in `hal-find-by-property --key info.parent --string $wlancard`; do
echo
lshal -u $udi
done
# end of code
Here the two outputs:
