SoC. Kernel is 6.6, maybe I did not get the kernelconfig right and
some options are not set correctly? Or maybe those crashes are real?
Then I could need some help how to _really_ enable coredumps for
journald, udevd, and timesyncd. Got a hint off-list to pass
'systemd.dump_core=true' to kernel cmdline, but that had no effect on
coredump creation.
I would just set kernel.core_pattern to a *file* path, e.g. "/var/log/core.%P". Then use the shell's ulimit command to raise the coredump size limit as it defaults to zero (ulimit -c unlimited), and manually start /usr/lib/systemd/systemd-timesyncd from the shell (timesyncd is the simplest one and doesn't do anything system-critical).
Alternatively, run the service under the debugger: `gdb /usr/.../timesyncd`.
