I have a late-model Intel 7260 wifi/bluetooth mini-PCIE card plugged into my Nvidia Jetson board. Bluetooth is basically working, but I've noticed the following odd pattern in my logs: (previous 12 days omitted for brevity; pattern is same as below) [...] Aug 16 03:33:00 kolonia kernel: [921790.543197] usb 1-1: USB disconnect, device number 12 Aug 16 03:33:00 kolonia kernel: [921790.761151] usb 1-1: new full-speed USB device number 13 using tegra-ehci Aug 16 03:33:00 kolonia kernel: [921790.889599] usb 1-1: New USB device found, idVendor=8087, idProduct=07dc Aug 16 03:33:00 kolonia kernel: [921790.896428] usb 1-1: New USB device strings: Mfr=0, Product=0, SerialNumber=0 Aug 16 03:33:00 kolonia kernel: [921790.922681] Bluetooth: hci0: read Intel version: 3707100180012d0d06 Aug 16 03:33:00 kolonia kernel: [921790.929091] Bluetooth: hci0: Intel device is already patched. patch num: 06 Aug 16 03:33:00 kolonia bluetoothd[1888]: Sap driver initialization failed.

This happens almost every day, but you can see it skipped August 17th for some reason. In that case the interval was exactly 2x, i.e. the pattern continues. Any idea why this would be happening? It doesn't seem to have any adverse effects, but I like a good mystery. -- 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
