Description Armands Liepins 2008-11-06 07:12:35 EST
Description of problem:
It seems wireless radio is disabled on HP nx6110 notebook. After boot LED indicating radio is on, but wireless does not work. Here is info from dmesg related to b43:

b43-pci-bridge 0000:02:04.0: PCI INT A -> GSI 21 (level, low) -> IRQ 21
b43-phy0: Broadcom 4318 WLAN found
b43-phy0 debug: Found PHY: Analog 3, Type 2, Revision 7
b43-phy0 debug: Found Radio: Manuf 0x17F, Version 0x2050, Revision 8

b43-phy0: Radio hardware status changed to DISABLED

Maybe this is somehow connected: initially, after boot, lid switch does not work, but when radio kill button is pressed, backlight goes off for the moment and lid switch starts to work.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
Actual results:
Wireless does not work, radio kill button does not turn on wireless radio.

Expected results:
Working wireless, radio kill button turns on/off wireless radio.

After enabling wireless in windows xp, it started to work, but LED sometimes does not work. After boot LED always goes on (when wl driver starts), then when button is pressed, it goes off and never goes on, but sometimes after boot it works. Strange.

This bug appears to have been reported against 'rawhide' during the Fedora 10 development cycle.
Changing version to '10'.

More information and reason for this action is here:

This might require some laptop-specific code, not sure.
Comment 4 John W. Linville 2009-02-25 13:52:40 EST
It looks like 2.6.29 kernels have a module intended to address buttons on HP laptops.  Could you try this kernel?

Comment 5 John W. Linville 2009-04-27 11:12:40 EDT
Hopefully that worked?  In any case, closed due to lack of response...
Comment 6 Armands Liepins 2009-05-17 07:36:46 EDT
Don't know which kernel module is responsible for buttons, but just installed from updates-testing and unfortunately nothing has changed.
Comment 7 Armands Liepins 2009-05-17 08:40:16 EDT
It seems kernel guys started working on this:
