https://bugzilla.kernel.org/show_bug.cgi?id=190831 Bug ID: 190831 Summary: Intel Bluetooth 8260 breaks with latest firmware Product: Drivers Version: 2.5 Kernel Version: 4.8.14 Hardware: All OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Bluetooth Assignee: linux-bluetooth@xxxxxxxxxxxxxxx Reporter: jan.steffens@xxxxxxxxx Regression: No My Bluetooth mouse only works for a few seconds (the exact time appears random) after the Bluetooth controller is reset. At first, it seems only its "frame rate" is reduced drastically, then it completely stops working. It also makes pairing nearly impossible. "hciconfig hci0 reset" briefly gets the mouse working again. Firmware revision "0.0 build 95 week 37 2016" from linux-firmware 91ddce4 (built 2016-12-05) is broken. The driver boots with these messages: Bluetooth: hci0: Bootloader revision 0.0 build 2 week 52 2014 Bluetooth: hci0: Device revision is 5 Bluetooth: hci0: Secure boot is enabled Bluetooth: hci0: OTP lock is enabled Bluetooth: hci0: API lock is enabled Bluetooth: hci0: Debug lock is disabled Bluetooth: hci0: Minimum firmware build 1 week 10 2014 Bluetooth: hci0: Found device firmware: intel/ibt-11-5.sfi Bluetooth: hci0: Waiting for firmware download to complete Bluetooth: hci0: Firmware loaded in 1474407 usecs Bluetooth: hci0: Waiting for device to boot Bluetooth: hci0: Device booted in 10684 usecs Bluetooth: hci0: Found Intel DDC parameters: intel/ibt-11-5.ddc Bluetooth: hci0: Failed to send Intel_Write_DDC (-22) Firmware revision "0.0 build 30 week 18 2016" from linux-firmware 9c71af9 (built 2016-10-05) works fine. The driver boots with these messages: Bluetooth: hci0: Bootloader revision 0.0 build 2 week 52 2014 Bluetooth: hci0: Device revision is 5 Bluetooth: hci0: Secure boot is enabled Bluetooth: hci0: OTP lock is enabled Bluetooth: hci0: API lock is enabled Bluetooth: hci0: Debug lock is disabled Bluetooth: hci0: Minimum firmware build 1 week 10 2014 Bluetooth: hci0: Found device firmware: intel/ibt-11-5.sfi Bluetooth: hci0: Waiting for firmware download to complete Bluetooth: hci0: Firmware loaded in 1555030 usecs Bluetooth: hci0: Waiting for device to boot Bluetooth: hci0: Device booted in 16567 usecs Bluetooth: hci0: Found Intel DDC parameters: intel/ibt-11-5.ddc Bluetooth: hci0: Applying Intel DDC parameters completed Bluetooth: hci0: Setting Intel event mask failed (-16) This problem seemed similar to https://bugzilla.kernel.org/show_bug.cgi?id=189641 but the loss of function doesn't correlate with any messages. However, while it is broken I do see the occasional repeat of Bluetooth: hci0 command 0x200c tx timeout with varying command numbers. As an aside, it appears the driver will only print the version if a firmware is already loaded. This is a bit irritating as after a complete power-off (to clear the firmware) btusb has to be unloaded and reloaded in order to print the version. Kernel is linux-zen 4.8.14 x86_64.
