October 9, 20251 yr Hardware: OrangePI-5-Plus (rk3588), with "32 GB" of RAM Operating System: Debian Trixie (pure, except EFI boot and Armbian edge kernel) Root File System: Ext4 (encrypted) Desktop: KDE Plasma 6.3.6 (wayland, GDM3), KDE Frameworks version: 6.13.0, QT version: 6.8.2 EFI Source: https://github.com/edk2-porting/edk2-rk3588 The boot messages, after a few starts (spaced apart) of the low-memory-monitor.service, say there's a failure to start it. After booting is complete, here's a screenshot of the output of: systemctl status low-memory-monitor.service This error didn't show up until I installed a number of packages. I tracked down the offending package from the Trixie repository: Package: xfsprogs Version: 6.13.0-2+b1 Size: 4774 kB Description: A set of commands to use the XFS filesystem, including mkfs.xfs Once this package was removed, the error vanished, and a repeat of the above Status command reported low-memory-monitor-service as active and okay. I also found that, while the error occurred with the Armbian edge 6.16.4 kernel, it did NOT occur with the Debian 6.16.3 kernel. Kernel With The Error (kernel source: Armbian trixie) --------------------- Package: linux-image-edge-rockchip64 (Armbian Linux edge kernel image 6.16.4-edge-rockchip64) Version: 25.8.1 Size: 282 MB Kernel Without The Error (kernel source: Debian trixie-backports) ------------------------ Package: linux-image-6.16.3+deb13-arm64-unsigned (Linux 6.16 for 64-bit ARMv8 machines) Version: 6.16.3-1~bpo13+1 Size: 210 MB I also briefly tried regressing the Armbian edge kernel from 25.8.1 (6.16.4) to the previously available version of 25.5.2, which was 6.16.0-rc3 (I think). The error occurred with that kernel as well. An Effect of This Bug (Possibly) When this error was showing up, I was once using the internet (firefox-esr package version 140.3.1esr-1~deb13u1) for a while, when after closing it, I discovered that my desktop background image had changed on its own. I could not change it back, no matter what I did (in the KDE settings gui). I could change it to something else, but whenever I changed it back, the altered image returned instead of what it should have been. But once I rebooted, the background was back to normal. While this one experience (very much an outlier) may not be conclusive, it is indicative of a possible memory leak. Edited October 9, 20251 yr by The Tall Man
