Bug Description

== SRU Justification [precise] ==
Impact:
 * Prevents using WiFi without Bluetooth, or vice-versa.

Fix:
 * This patch adds a Dell laptop model to rfkill blacklist table; affects only this model.

Testcase:
 * Disable Bluetooth via the indicator icon; verify that WiFi continues to operate.

-----------------------------------------------------------------------------------------

In Precise there seems to be a bug in dell-laptop.

When you kill dell-bluetooth, it also hard blocks 'Wireless LAN'.
This should NOT be the case and only block your bluetooth.

$ sudo rfkill list
0: dell-wifi: Wireless LAN
    Soft blocked: no
    Hard blocked: no
1: dell-bluetooth: Bluetooth
    Soft blocked: no
    Hard blocked: no
2: dell-wwan: Wireless WAN
    Soft blocked: no
    Hard blocked: no
5: hci0: Bluetooth
    Soft blocked: no
    Hard blocked: no
6: phy0: Wireless LAN
    Soft blocked: no
    Hard blocked: no

$ sudo rfkill block 1
$ sudo rfkill list
0: dell-wifi: Wireless LAN
    Soft blocked: no
    Hard blocked: no
1: dell-bluetooth: Bluetooth
    Soft blocked: yes
    Hard blocked: no
2: dell-wwan: Wireless WAN
    Soft blocked: no
    Hard blocked: no
6: phy0: Wireless LAN
    Soft blocked: no
    Hard blocked: yes

$ /sys/kernel/debug/dell_laptop# cat rfkill

This behaviour has been addressed in Bug # 901410 ... however we'll need to handle a new product name, L322X.

This bug is awaiting verification that the kernel for Precise in -proposed solves the problem (3.2.0-30.47). Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-precise' to 'verification-done-precise'.

If verification is not done by one week from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

Verified with L322X and the -proposed kernel. I can disable bluetooth via the indicator menu and it no longer takes the wifi down with it.

Thanks, guys!
