https://bugzilla.kernel.org/show_bug.cgi?id=197997 Bug ID: 197997 Summary: Intel 8265 bluetooth dropping connections, but works with newer firmware from Windows Product: Drivers Version: 2.5 Kernel Version: 4.13.12-1-ARCH Hardware: All OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Bluetooth Assignee: linux-bluetooth@xxxxxxxxxxxxxxx Reporter: kohler.jonathan@xxxxxxxxx Regression: No Created attachment 260873 --> https://bugzilla.kernel.org/attachment.cgi?id=260873&action=edit Systemd logs and dmesg reports about bluetooth errors and firmware I've been having issues in the last few weeks with my bluetooth (Intel dual-band 8265 wifi/bluetooth) adapter consistently dropping connections after a few seconds, after which most bluetooth commands (using bluetoothctl or hciconfig) timeout until the computer is rebooted. (Example output of journalctl | grep -i blue attached) I dual-boot my laptop with Windows, and have noticed that if I do a warm reboot from Windows into Linux, the bluetooth adapter works fine. Looking into `dmesg | grep -i blue' (see attachment) indicates that a newer firmware (Firmware revision 0.1 build 151 week 24 2017) persists after rebooting. However, after a cold start the kernel loads the firmware in linux-firmware (dmesg_coldboot_before.txt), and a subsequent restart shows an older firmware revision (Firmware revision 0.1 build 103 week 50 2016, dmesg_reboot_linux.txt). If I copy the *.sfi firmware from the windows driver over /lib/firmware/intel/ibt-12-16.sfi, the kernel loads the newer firmware and bluetooth works after a cold boot too. But I can't find any officially licensed source for the updated firmware. Can this be updated in linux-firmware somehow? -- 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
