    Question (Impish) Chrome_IOThread issues?

    Has anyone else started experiencing issues running Chromium-based apps in the last week or three? I wanted to see if this is widespread before I create a Launchpad bug report. I searched for an existing report there, but didn't see anything that looked similar.

    The Symptoms: I first noticed the problem when I tried to launch teams-insiders (Microsoft Teams beta) for the first time in a week. It would not launch and I found the following in the dmesg output:

    Code:
    [  653.714267] traps: Chrome_IOThread[13582] trap invalid opcode ip:55e77adb8934 sp:7fe4cd0cd4d0 error:0 in teams-insiders[55e7787c2000+5fbe000]
    Some searches turned up older similar issues where Teams would not work for others until a reboot. So, I rebooted for the first time in 20 day.

    Unfortunately, it didn't change the symptoms. In fact, I noticed Vivaldi (also chromium-based) would no longer start either.

    I launched an electron-wrapped app I had created long ago myself via nativefier... and it also failed to start. It also leaves a Chrome_IOThread dmesg log:

    Code:
    [  382.903339] traps: Chrome_IOThread[12705] trap int3 ip:561036813664 sp:7f097ebb3490 error:0 in 8BitWorkshop[561034242000+5f85000]
    Oddly, Chrome, Vivaldi-Snapshot, and *even the Chromium web browser* all work fine. :\

    Reinstalling teams-insiders made no difference.

    I was wondering if it was another kernel 5.13 issue, so I installed the mainline 5.14.2 kernel... same issue. I also tried rebooting into 5.11.... same issue.

    code-insiders also now appears to have the same problem as Teams:

    Code:
    [ 1060.228147] traps: Chrome_IOThread[14829] trap invalid opcode ip:55b09720c653 sp:7f8cb7003200 error:0 in code-insiders[55b094a65000+5ee2000]
    All non-chromium apps appear to work fine - even Vulkan games (using nVidia 470.63.01 drivers). I completely removed/reinstalled the video drivers, but that's made no difference either.

    Anyone else experiencing this?

    Edit: I suspect this is related to hardware acceleration - and that the chromium based browsers I have that still work simply do not have it enabled. Perhaps a change in the newest nVidia drivers broke something?

    Edit2: Err... scratch that... looks like Chrome, which works... has hardware acceleration enabled. :\

    SystemD enters the chat...

    Looks like I found someone else who hit this yesterday: https://github.com/microsoft/vscode/issues/132609

    He suspects an incompatibility between systemd 249 and chrome <93 / electron <14.0 when paired with hosts using nvidia GPUs and the nVidia drivers.

    Edit: And it looks like he's right. I just rebuilt my own previously failing 8bitworkshop app with electron 15 and it now works fine.

    This thread is the first search result when searching for the reason why Teams isn't starting. In case anyone else gets here looking for a Teams fix, you need to vote up this bug at Microsoft's site: https://microsoftteams.uservoice.com...ith-apps-teams
