Product: Networking Version: 2.5 Kernel Version: 4.15-rc3 Hardware: Intel OS: Linux Tree: Mainline Status: NEW Severity: high Priority: P1 Component: Other Assignee: stephen@xxxxxxxxxxxxxxxxxx Reporter: rex_tsai@xxxxxxxxxxx Regression: No CPU : Intel Gemini Lake SoC B0 Stepping OS : Ubuntu 16.04.3/ Kernel:4.15-rc3 WLAN module: JfP 9560 QS smaple BT driver : Inbox BT firmware: ibt-17-16-1.ddc&ibt-17-16-1.sfi [Steps to reproduce] 1. On Ubuntu 16.04.3, connect a BT headset to Intel 9650 make sure headset works. 2. sudo rmmod xhci_pci. 3. sudo modprobe xhci_pci 4. The headset will not reconnect to the Ubuntu automatically --> Issue happened 5. Re-power the connected BT headset, The headset will reconnect to Ubuntu successfully. [Analyzation] This symptom will not happen on Intel 7265 before. [Probable cause]: With 7265, when received reset command, 7265 will be reset, and the link between Ubuntu and headset will lost. The headset will detect link broken and reconnect to Ubuntu. With 9560, when received reset command, 9560 will be reset. But the link between Ubuntu and headset seems not be reset. So headset feels link alive and will not reconnect to Ubuntu automatically. -- 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
