Hiya, Since the last little while (I think since kernel 2.6.38) the rfkill switch on my laptop doesn't work too well.
I can turn the machine on with wireless (+bluetooth) enabled and if I hit the rfkill switch (Fn+F2 on my machine) both wifi and bt turn off as they should. If I turn it back on again however, both of the lights turn on briefly but then the wifi one goes out and bt follows shortly thereafter. The only way I can find to get wifi back is to reboot or: [root@jimmy ~]# rmmod btusb [root@jimmy ~]# rmmod bluetooth [root@jimmy ~]# rmmod dell_laptop [root@jimmy ~]# rmmod iwlagn [root@jimmy ~]# rmmod iwlcore [root@jimmy ~]# rmmod mac80211 [root@jimmy ~]# rmmod cfg80211 [root@jimmy ~]# rmmod rfkill [root@jimmy ~]# lsmod | grep rfk <press button to enable> [root@jimmy ~]# modprobe iwlagn When I disable the radio dmesg says this: iwlagn 0000:0b:00.0: RF_KILL bit toggled to disable radio. iwlagn 0000:0b:00.0: Not sending command - RF KILL iwlagn 0000:0b:00.0: Error sending REPLY_QOS_PARAM: enqueue_hcmd failed: -5 iwlagn 0000:0b:00.0: Not sending command - RF KILL iwlagn 0000:0b:00.0: Error sending REPLY_RXON: enqueue_hcmd failed: -5 iwlagn 0000:0b:00.0: Error setting new RXON (-5) iwlagn 0000:0b:00.0: Not sending command - RF KILL iwlagn 0000:0b:00.0: Error sending REPLY_RXON_ASSOC: enqueue_hcmd failed: -5 wlan0: deauthenticating from 1c:af:f7:1a:bc:6e by local choice (reason=3) keyboard: can't emulate rawmode for keycode 240 keyboard: can't emulate rawmode for keycode 240 iwlagn 0000:0b:00.0: Not sending command - RF KILL iwlagn 0000:0b:00.0: Error sending REPLY_REMOVE_STA: enqueue_hcmd failed: -5 iwlagn 0000:0b:00.0: Error removing station 1c:af:f7:1a:bc:6e iwlagn 0000:0b:00.0: Not sending command - RF KILL iwlagn 0000:0b:00.0: Error sending REPLY_RXON_ASSOC: enqueue_hcmd failed: -5 iwlagn 0000:0b:00.0: Not sending command - RF KILL iwlagn 0000:0b:00.0: Error sending REPLY_RXON: enqueue_hcmd failed: -5 iwlagn 0000:0b:00.0: Error setting new RXON (-5) cfg80211: Calling CRDA to update world regulatory domain iwlagn 0000:0b:00.0: Not sending command - RF KILL iwlagn 0000:0b:00.0: Error sending REPLY_RXON: enqueue_hcmd failed: -5 iwlagn 0000:0b:00.0: Error setting new RXON (-5) iwlagn 0000:0b:00.0: Failing on timeout while stopping DMA channel 1 [0xa5a5a5a2] iwlagn 0000:0b:00.0: Failing on timeout while stopping DMA channel 3 [0xa5a5a5a2] iwlagn 0000:0b:00.0: Failing on timeout while stopping DMA channel 4 [0xa5a5a5a2] iwlagn 0000:0b:00.0: Failing on timeout while stopping DMA channel 6 [0xa5a5a5a2] cfg80211: World regulatory domain updated: cfg80211: (start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp) cfg80211: (2402000 KHz - 2472000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) cfg80211: (2457000 KHz - 2482000 KHz @ 20000 KHz), (300 mBi, 2000 mBm) cfg80211: (2474000 KHz - 2494000 KHz @ 20000 KHz), (300 mBi, 2000 mBm) cfg80211: (5170000 KHz - 5250000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) cfg80211: (5735000 KHz - 5835000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) usb 5-2: USB disconnect, address 5 btusb_intr_complete: hci0 urb ffff8800286416c0 failed to resubmit (19) btusb_bulk_complete: hci0 urb ffff880028641f00 failed to resubmit (19) btusb_bulk_complete: hci0 urb ffff8800286419c0 failed to resubmit (19) btusb_send_frame: hci0 urb ffff88009a8ffe40 submission failed When I enable it again (and it fails) it says this: iwlagn 0000:0b:00.0: RF_KILL bit toggled to enable radio. keyboard: can't emulate rawmode for keycode 240 keyboard: can't emulate rawmode for keycode 240 usb 5-2: new full speed USB device using uhci_hcd and address 6 usb 5-2: New USB device found, idVendor=413c, idProduct=8126 usb 5-2: New USB device strings: Mfr=1, Product=2, SerialNumber=0 usb 5-2: Product: BCM2045 usb 5-2: Manufacturer: Broadcom Corp iwlagn 0000:0b:00.0: RF_KILL bit toggled to disable radio. usb 5-2: USB disconnect, address 6 iwlagn 0000:0b:00.0: START_ALIVE timeout after 4000ms. Note that this is *without* pressing it wtiwce as the log's indicate - it's almost like the keypress is being detected twice enable/disable. or somethig (or the iwlagn driver somehow redisabled it after activation?) After pressing the button a third time (to disable the radio again (after the failed activation)) all I get is: keyboard: can't emulate rawmode for keycode 240 keyboard: can't emulate rawmode for keycode 240 So I'm a little stumped. Anyone else get this problem? iwlagn : Intel Corporation|PRO/Wireless 4965 AG or AGN [Kedron] Network Connection [NETWORK_OTHER] (vendor:8086 device:4229 subv:8086 subd:1101) (rev: 61) I found this which seems like a likely candidate for a fix... http://ns.spinics.net/lists/linux-wireless/msg64176.html but it's from February... is it really not in the .38.x kernel yet??
