Re: Explanation of killswitch related messages.

[MartinG <gronslet gmail com>]

Similar problem here, on a Dell Latitude X1:
# uname -a
Linux x1 2.6.22.5-76.fc7 #1 SMP Thu Aug 30 13:47:21 EDT 2007 i686 i686
i386 GNU/Linux

# cat /etc/rc.local
#!/bin/sh
touch /var/lock/subsys/local
modprobe cpufreq-powersave
modprobe  dcdbas
service haldaemon restart

# lsmod|grep dcdbas
dcdbas                 12257  0

# tail /var/log/messages
Sep 19 20:08:28 x1 NetworkManager: < info >  Error getting killswitch
power: org.freedesktop.Hal.Device.KillSwitch.NotSupported - Access
type not supported
Sep 19 20:09:04 x1 last message repeated 6 times
Sep 19 20:10:10 x1 last message repeated 11 times
...

# rpm -q libsmbios-bin
(not installed)

So I went ahead and installed it:
# wget -q -O - http://linux.dell.com/repo/software/bootstrap.cgi | bash
(what a stupid way to install a yum repo! Piping a web-page to bash...
I actually saved the script, and had a brief look at it before I ran
it.)

# yum install libsmbios-bin
# rpm -qa libsmbios\*
libsmbios-bin-0.13.10-1.fc7
libsmbios-libs-0.13.10-1.fc7

Now, my /var/log/messages reads:
Sep 19 20:49:07 x1 NetworkManager: < info >  Error getting killswitch
power: org.freedesktop.Hal.Device.KillSwitch.NotSupported -
dellWirelessCtl returned 4
Sep 19 20:49:38 x1 last message repeated 5 times
Sep 19 20:50:40 x1 last message repeated 10 times

So, I tried to restart 'haldaemon', and used the killswitch (Fn-F2) to
turn wireless off and on, but the message didn't go away.

I also tried restarting 'NetworkManager':
# service NetworkManager restart
But that didn't help either. I have
NetworkManager-0.6.5-7.fc7
knetworkmanager-0.2-0.1.svn20070815.fc7

Anything else to try?

best regards
