Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 7bit Precedence: bulk List-ID: X-Mailing-List: linux-wireless@vger.kernel.org Hi, I notice a regression report on bugzilla [1]. Quoting from it: > julien.falque@gmail.com 2023-05-14 09:55:38 UTC > > Since a Kernel update a few weeks ago, my laptop freezes when resuming from hibernation. It seems to handle the resume process normally but at the moment I should see Gnome login screen, I either get a black screen with just a white underscore instead, or nothing displayed at all (no backlight). I can't do anything at that point and I have to hard reboot. > > Steps to reproduce: > - hibernate > - resume > - wait until the resuming process should finish: black screen instead of e.g. Gnome's login screen > > journalctl gives nothing between the beginning of the resume and the crash, as if it never happened. > > I have a Dell XPS 15 (9550) with Arch Linux. The issue happens on linux (since v6.2.0 I think) but linux-lts (currently v6.1.28) is fine. > > A bisect on linux-git gave commit da6d9c8ecd00 as the cause of the problem. See bugzilla for the full thread. Julien: I asked you to also provide dmesg log as I don't know what exactly happened, but you mentioned the culprit was da6d9c8ecd00e2 ("wifi: brcmfmac: add firmware vendor info in driver info"), which implies that the crash involves your wifi device. From my experience though, GDM crashes are usually caused by xwayland. Anyway, I'm adding this to regzbot: #regzbot introduced: da6d9c8ecd00e2 https://bugzilla.kernel.org/show_bug.cgi?id=217442 #regzbot title: brcmfmac firmware vendor info addition triggers GDM crash on resuming from hibernation Thanks.
