From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: From: bugzilla-daemon@bugzilla.kernel.org To: linux-bluetooth@kernel.org Subject: [Bug 199351] intel 8265 bluetooth no longer functions as of 4.16 Date: Fri, 13 Apr 2018 03:29:32 +0000 Message-ID: In-Reply-To: References: Content-Type: text/plain; charset="UTF-8" MIME-Version: 1.0 Sender: linux-bluetooth-owner@vger.kernel.org List-ID: https://bugzilla.kernel.org/show_bug.cgi?id=199351 --- Comment #7 from jebrosen2014@gmail.com --- I believe I have found the culprit: commit eff2d68ca7388ee1c08811c6bbf4d8587cba01da enables btusb autosuspend by default given a certain Kconfig option, and I confirmed that Arch Linux did opt in to it. Appending `btusb.enable_autosuspend=n` to my kernel command line has effectively solved my issue as far as I am concerned. I had discovered that autosuspend "broke" my bluetooth device a long time ago, but it hasn't crossed my mind for a while. The actual bug here is that autosuspend causes the bluetooth device to stop working. -- You are receiving this mail because: You are the assignee for the bug.
