https://bugzilla.suse.com/show_bug.cgi?id=1235020 Bug ID: 1235020 Summary: Hard freeze workqueue lockup mediatek bluetooth Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: Other OS: openSUSE Tumbleweed Status: NEW Severity: Normal Priority: P5 - None Component: Kernel Assignee: kernel-bugs@opensuse.org Reporter: andrea.ippo@gmail.com QA Contact: qa-bugs@suse.de Target Milestone: --- Found By: --- Blocker: --- Hi, I've been experiencing random lockups on TW for a while now (more than a month): https://community.frame.work/t/workqueue-lockup-opensuse-tw/60430 (I'm the OP here) https://forums.opensuse.org/t/workqueue-lockup-should-i-file-a-bug/180387 I had to switch to Fedora for the past couple of weeks, and surprisingly I never experienced this issue there, which makes me think it might be related to the opensuse kernel (or maybe, just bad luck on TW). The problem seems to be related to bluetooth, as we can see by checking at the logs at the timestamp preceding the BUG - lockup entry by X seconds as specified in the error: Examples: https://pastebin.com/79dj1PeX https://pastebin.com/n3m1S8B7 In both cases if we go back by 58s we get around this part: Jan 02 18:19:33 andromeda kernel: Bluetooth: hci0: Execution of wmt command timed out Jan 02 18:19:33 andromeda kernel: Bluetooth: hci0: Failed to send wmt patch dwnld (-110) Jan 02 18:19:33 andromeda kernel: Bluetooth: hci0: Failed to set up firmware (-110) Jan 02 18:19:33 andromeda kernel: Bluetooth: hci0: HCI Enhanced Setup Synchronous Connection command is advertised, but not supported.
