Public bug reported: Since the kernel upgrade to 5.6.0-1048-oem my Dell XPS 13 9380 starts to hang and finally freezes when I want to connect to my AV-receiver over bluetooth. There is something funky going on in the kernel, hence I attached the dmesg kernel messages since system boot.
All consecutive versions > 5.6.0-1048-oem show the same behaviour, hence I'm still booting 5.6.0-1047-oem currently. I tried the 5.4 kernel series and the latest one (5.4.0-72-generic) was also working fine. The only HW change I did to my Dell XPS 13 9380 was changing my SSD to a bigger Samsung SSD 970 EVO Plus 1TB, everything is as I ordered it. I read about bluetooth vulnerability fixes in exactly the version where the problem started here: https://ubuntu.com/security/notices/USN-4752-1 Maybe that has something to do with the issue? Can somebody reproduce this issue? lsb_release -rd ``` Description: Ubuntu 20.04.2 LTS Release: 20.04 ``` ** Affects: linux-meta-oem-5.6 (Ubuntu) Importance: Undecided Status: New ** Tags: 9380 bluetooth crash dell xps ** Attachment added: "dmesg output" https://bugs.launchpad.net/bugs/1925056/+attachment/5489843/+files/bluetooth_crash_dmesg.txt ** Package changed: gnome-shell (Ubuntu) => linux-meta-oem-5.6 (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1925056 Title: Dell XPS 13 9380 - System hangs when connecting bluetooth since kernel 5.6.0-1048-oem To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-meta-oem-5.6/+bug/1925056/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
