As far as I can tell, usually when it happens the following events leads up to it: - I am using my laptop, with the BT mouse paired - I suspend my laptop, while the mouse is still paired - I turn off the physical power switch on my BT mouse (this may be crucial) - Later on, I resume my laptop - Due to a KDE bug, I have to enable my BT adapter (it starts powered, but in the hciconfig DOWN state). I don't know if this has anything to do with it, if I remember correctly the BT controller would lock up even when KDE resumed with the bluetooth stack UP. - After that, I turn on the BT mouse power switch - It pairs and begins to work - After a few minutes the BT controller locks up - I can reset the device doing rfkill block/unblock as stated in comment #1 - After that, the BT re-pairs and works consistently (without resetting the BT mouse, I just wait a few seconds and it re-connects) Usually in my dmesg I see messages such as the following, correlating to the BT controller lockup: [34740.224713] Bluetooth: hci0 command 0x0c1a tx timeout [34742.272545] Bluetooth: hci0 command 0x0406 tx timeout [34745.472341] Bluetooth: hci0 command 0xfc3f tx timeout [44095.674692] Bluetooth: hci0 command 0x0c03 tx timeout [44120.249020] Bluetooth: hci0 command 0x0c03 tx timeout [101098.110912] Bluetooth: hci0 command 0x0804 tx timeout [101100.158788] Bluetooth: hci0 command 0x041f tx timeout [101102.206688] Bluetooth: hci0 command 0x0406 tx timeout [101274.035219] Bluetooth: hci0 command 0x0c03 tx timeout (Note from the timings, you can see that these are from multiple failures) Also note, that when I connect the mouse I see the following (unknown main item tag 0x0). This happens even when the controller is working without lockups so may be unrelated: [113184.095301] hid-generic 0005:045E:07A2.0019: unknown main item tag 0x0 [113184.095518] input: Microsoft Sculpt Comfort Mouse as /devices/pci0000:00/0000:00:14.0/usb2/2-6/2-6:1.0/bluetooth/hci0/hci0:256/0005:045E:07A2.0019/input/input38 [113184.096339] hid-generic 0005:045E:07A2.0019: input,hidraw1: BLUETOOTH HID v1.29 Mouse [Microsoft Sculpt Comfort Mouse] on 5c:51:4f:0a:9f:8c -- You are receiving this mail because: You are the assignee for the bug. -- To unsubscribe from this list: send the line "unsubscribe linux-bluetooth" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
