System Settings Crashes Since BIOS Update V1.56

We made a fresh install of Windows 10 last Saturday knowing that there was an update for our Firmware bug. We don’t need to tweak the bootline anymore.

Here’s the bug fix:

BIOS 1.54:
[Problem fixes]
-** Sync IOAPICID in IVRS and APIC ACPI tables (Linux). **

  • Enhance to address vulnerability security issue.
    1.56
    [Problem fixes]
  • Fixed Dolby Audio no function issue.
  • Fixed an issue that Backspace on Numpad key don’t send WM_KEYUP when release key.

Since then, 20191112 to 18th, the settings app crashes for all windows. Re-open the app works only once. The app generates an error each time and ask to restart the application. About 12 of them were sent this morning after the fresh install of 20191118.

After post-installation, the app keeps crashing, less often with no error.

The rest works correctly.

 rpm -qa | grep -i kde-agent
polkit-kde-agent-5-lang-5.17.3-1.1.noarch
polkit-kde-agent-5-5.17.3-1.1.x86_64

Please show the errors here. And show

From Yast Journal entries. Same error for all windows.

This bug was also present before KDE 5.17.3 or before Monday (20191112-20191116). Not dual boot.

rpm -qa | grep -i kernel-default
kernel-default-devel-5.4.rc8-1.1.g97aef18.x86_64
kernel-default-5.4.rc8-1.1.g97aef18.x86_64

For the same off-line setup, the bug is not present in Kubuntu 19.10 (kde 5.16.5). Upgrading to 20.04 comes with no bugs either.

sudo sed -i 's/eoan/focal/g' /etc/apt/sources.list

I’ve also been seeing this in Tumbleweed.
Began with Plasma 5.17.2 and persists with 5.17.3

In systemsettings I can enter a window. Back out and try to enter another window and systemsettings immediately crashes.
Get a popup “Dr Konqui” notification that the app has crashed and an option to restart it.

Not sure if this is of any use

systemsettings5 PID: 4,510 Signal: Segmentation fault (11)


from systemd

[system] Failed to reset fd limit before activating service: org.freedesktop.DBus.Error.AccessDenied: Failed to restore old fd limit: Operation not permitted

oh . . . there are actually some specific references to systemsettings5

@farcusnz
Thanks for replying!

Dr. Konqui needs attention, error should come with an option <<copy to clipboard>> and as a bonus, a short description area. Answering yes is a no end loop and no, is ambiguous. We don’t know if the fatal error was sent. Plus, Dr. Konqui is shown only after the fresh install here, never when the settings menu overview is done. App crashes occasionally with no error or Dr.Konqui pop-up. 20191112 + 20191116

We’ve never seen Dr. Konqui nor the actual bug before the BIOS update (V1.53 since June). Good to know that it may not be a Lenovo issue.

Will try to copy the error on our next fresh install. We really appreciate your answer, thanks again.

Indeed. It’s crashing here too following your instructions. TW 20191116.

Here’s the error:

The rest seems equivalent to the above.

The crash issue made its first appearance here after the fresh install of the 20191112 ISO (immediately after BIOS update on the 16th). The bug is also present in the 20191118 ISO.

In between, there are about 650 new packages.

The bug is present in 20191122 and also present in Kubuntu 20.04 20191116. There was only one Dr.Konqui crash report. No crash after nor after updating.
Run normally there.

Report to https://bugs.kde.org/

We we’re not able to reproduce the bug in Kubuntu 20.04 with secure boot disabled, nor enabled with a second fresh install (offline). In both cases, tweaking KDE works normally for all tiles. System settings crashes or disappears when trying to re-open it.

Logout fixes it and not a new bug.

The bug is more severe in TW, Dr.Konqui populates the taskbar. Is updating the BIOS on Nov.16th a coincidence?

To be confirm…

With the new patch, the Machine boots untweaked and works normally after.

cat /proc/cmdline
BOOT_IMAGE=/boot/vmlinuz-5.4.0-050400rc8-generic root=UUID=2ba76c0e-a044-4526-a6d4-0052de4192bc ro quiet splash vt.handoff=7

Previous BIOS V1.53 gives the same result. Not a bad news, the Lenovo patch fixes our firmware bug. Back to V1.56.

Too many noises on-board, we managed this issue by kicking them all out.

Under windows 10 with the help of the well know data eraser, all hard drive sectors were over-written with “00” (1x). No bugs after the fresh install of 20191123 snapshot.

All the best,

Kubuntu 20.04 Daily Build: DrKonqi Btrfs Partitions + 20191206

If we don’t do a fresh install, we don’t get the bug. But this issue seems to duplicate for many users. It was introduced on our motherboard at the end of 5.17.2 for many offline fresh installs.

For Kubuntu FF 20191206 and FF 20191215, System Settings crashes with Btrfs partitions at Application style>GNOME/GTK Application Style>Fallback theme>Breeze>Apply>Windows Decoration>DrKonqi.

The exact same bug was reported the next day at KDE Bugtracking with Manjaro.

The bug cannot be duplicate with Ext4 partition(s) in FF (20191206 + 20191208). Once we had the bug, it does not come back anymore.

Hi
A couple of observations, please don’t post links to windows freeware/payware, just use the name if folks are interested they can use a search engine, can you post the bug report number created at KDE?

You seem to be quoting a lot of Windows and Ub* data, not much Tumbleweed data… this is an openSUSE forum and likely to glean information from folks running the latest snapshot (sans bleeding edge kernel), perhaps this data can be posted/referenced at the bug report?

The DrKonqi crash report was empty in the previous post. We just made a fresh install with today’s build:KDE Live 20191214 (946MB).

System Settings crashed at Application style. Here’s the crash report 221 lines/2.
