Hi all,

the dell_laptop kernel module creates an rfkill
device that reports the wrong state:

$ readlink /sys/class/rfkill/rfkill0
.../../devices/virtual/rfkill/rfkill0

$ cat /sys/class/rfkill/rfkill1/state
2

This prevents the use of NetworkManager, since it relies on the rfkill
data from the kernel when disabling the part of its user interface that
allows the user to scan for and connect to wireless networks.
###

$ cat /var/lib/NetworkManager/Network-Manager.state
WLAN..=false
# when I set it to true and restart the NetworkManager its alwas resetting to "false".
# In the contect-menu of the nm-applet its greyed-out, so I cannot switch on.

##
$ rfkill list

reports alwasys for Bluetooth and WLAN:
Hard blocked: yes

# when I try to set it with "rfkill unblock all" nothing happens.

# But remove the kernel-module "dell_laptop" WLAN and Bluetooth is getting working.

# I found this Bug upstream, and I get this bug with the last Kernel-Updates "2.6.32-22"
