https://bugzilla.kernel.org/show_bug.cgi?id=194839 Bug ID: 194839 Summary: Intel 8265 M.2 card: Bluetooth stops working after about 30 seconds Product: Drivers Version: 2.5 Kernel Version: 4.10.1 Hardware: All OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Bluetooth Assignee: linux-bluetooth@xxxxxxxxxxxxxxx Reporter: sven.koehler@xxxxxxxxx Regression: No When resuming from suspend to RAM, bluetooth works just fine for about 30 seconds. Then, my bluetooth mouse stops. If I reboot the machine, then the Windows drivers fail to load with the error "STATUS_DEVICE_POWER_FAILURE" whatever that means. If I suspend and resume the machine while running Windows 10, that actually fixes the issue and the bluetooth device starts to work! I can subsequently use my bluetooth mouse for hours. Reboot into Linux again, I can also use the bluetooth mouse just fine. But after another suspend/resume while running Linux, things are broken again. The mouse stops working after 30 seconds. I can issue a USBDEVFS_RESET ioctl to the device, and bluetooth will start working again - and then stops again after 30 seconds. I can poweroff the PC and then boot into Linux and the bluetooth mouse works properly until the next suspend/resume cycle. -- 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
