I'm seeing the same thing here on my HP dv2120, also a 4311 chipset. Glad to provide further details if needed, otherwise will gladly test potential fixes .... Same behavior with kernel 2.6.23.1-58.fc8 from Koji build. I have the same problem on a Dell Inspiron B130 with kernel 2.6.23.1-49.fc8 and a broadcom 4318 wireless. I have the same problem with a Dell Latitude D620 (b43 driver, 1390/4311 chip) Also, the radio kill hard switch is not detected anymore. I have looked in the source, and the problem seems to be in the new rfkill code: It uses an input polled device and the rfkill module. However the poll function (in b43/rfkill;c) which tests the radio kill hard switch is never called. I tried to trace, and it seems that the input polled device open routine (which starts the poll periodic function) is not called. I shall investigate further. The following method allows the led and the radio kill hard switch to work: - Load the rfkill-input module (modprobe rfkill-input) BEFORE the load of the b43 module. Then, when the input polled device in b43 is registered, it is connected to the input_handler in rfkill-input and thus opened, staring the periodic poll. However in kernel 2.6.23.1-49.fc8 the b43 module depends on the rfkill module but not on the rfkill-input module. May be some dependancy is missing. I tested today kernel 2.6.23.12-99.fc8 from Koji and the wireless led is back working! I noticed that it adds a handler for wireless radio led Registered led device: b43-phy0:radio I guess that was the culprit... Good job! This bug can be closed for what regards me... |
