Description Matt Domsch 2007-08-01 16:29:00 UTC 
Description of problem:
hal doesn't load the dcdbas kernel module automatically.  This causes continuous
syslog error messages:

NetworkManager: <info> Error getting killswitch power:
org.freedesktop.Hal.Device.UnknownError - AN error occurred.  The error message
is: #012 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):
hal-0.5.9-8.fc7

How reproducible:
always on Dell laptops

Steps to Reproduce:
1. start networkmanager
2.
3.
  
Actual results:
errors seen in syslog

Expected results:
no errors

Additional info:
Attachment dell.modules can be dropped into /etc/sysconfig/modules/ to be
automatically loaded by initscripts.  This stops such error messages.

dell.modules
Comment 2 David Zeuthen 2007-08-01 18:55:37 UTC 
Actually I would say that libsmbios should insmod dcdbas itself and/or drop that
file into /etc/sysconfig/modules. Much like e.g. mount(1) loads file-system
drivers when needed. Or how losetup loads loop.ko when needed.

Anyway this is all moot, since DMI modalias support is landing / has landed in
recent Linux kernels. I believe dcdbas should just export modalias to make this
load automatically as part of the boot process.

Hence, reassigning to the kernel to make sure we do that.
