Description David Anderson 2007-10-10 05:53:22 EDT
Description of problem:

I have a Dell Inspiron 1501. This error message appears in /var/log/messages 
every 6 seconds:

Oct 10 10:39:35 hodge NetworkManager: <info>  Error getting killswitch power: 
org.freedesktop.Hal.Device.UnknownError - An Error occurred. The Error message
is:    Could not open file /sys/devices/platform/dcdbas/smi_data. Check that 
dcdbas driver is properly loaded.

Version-Release number of selected component (if applicable):
NetworkManager 0.6.5-7.fc7
hal 0.5.9-8.fc7

If I do "/sbin/modprobe dcdbas", the errors stop. I presume that something 
ought to be doing that automatically, but isn't?
Comment 1 Dan Williams 2007-10-10 12:16:28 EDT
kernel folks; any idea why dcdbas isn't getting auto-loaded?

There doesn't seem to be anything that would tell the system to load it. (It
doesn't contain a list of devices that it applies too.)

I'm reviewing this bug as part of the kernel bug triage project, an attempt to
isolate current bugs in the Fedora kernel.


I am CC'ing myself to this bug and will try and assist you in resolving it if I can.

There hasn't been much activity on this bug for a while. Could you tell me if
you are still having problems with the latest kernel?

If the problem no longer exists then please close this bug or I'll do so in a
few days if there is no additional information lodged.
Comment 4 David Anderson 2008-01-22 05:44:14 EST
I think that there was some upstream work on getting the relevant module 
loaded automatically. I worked round the problem for the meanwhile with a line 
in rc.local.
Comment 5 Christopher Brown 2008-01-22 09:29:14 EST
Thanks for the update David. Do you have the line that you added as a workaround
for anyone else with the same issue - I'm guessing:

/sbin/modprobe dcdbas

or something similar?

Are you still having this issue with the line commented out?
Comment 6 Chuck Ebbert 2008-01-22 12:49:47 EST
