This is a multi-part message in MIME format. --nextPart2916378.fspEBoepoX Content-Transfer-Encoding: 7Bit Content-Type: text/plain; charset="UTF-8" I get occasional random crashes when opening some applications in KDE. The most common culprits are libreoffice. gimp and audacity though they frequently start without any problem. Everything freezes as soon as the application starts and after a few seconds the system reboots. Here's some typical crash files: curlew:/var/crash# cat core.txt.2 'version' has unknown type; cast it to its declared type 'version' has unknown type; cast it to its declared type 'version' has unknown type; cast it to its declared type 'version' has unknown type; cast it to its declared type Unable to find matching kernel for /var/crash/vmcore.2 curlew:/var/crash# cat info.2 Dump header from device: /dev/gpt/swap1 Architecture: amd64 Architecture Version: 2 Dump Length: 1692549120 Blocksize: 512 Compression: none Dumptime: 2023-06-08 12:29:44 +0100 Hostname: curlew Magic: FreeBSD Kernel Dump Version String: FreeBSD 13.2-RELEASE releng/13.2-n254617-525ecfdad597 GENERIC Panic String: page fault Dump Parity: 3806917495 Bounds: 2 Dump Status: good I've tried to debug the dump following the instructions in section 10.2 of the handbook https://docs.freebsd.org/en/books/developers-handbook/kerneldebug/#kerneldebug-gdb[1] but with no success: curlew:/var/crash# kgdb /boot/kernel/kernel /var/crash/vmcore.2 *GNU gdb (GDB) 13.1 [GDB v13.1 for FreeBSD]* Copyright (C) 2023 Free Software Foundation, Inc.
