Updated to latest and see a few segfaults related to ldconfig -r during the pacman run. However, the system rebooted fine. The kernel is reported as 6.10.1 which is pretty late. Thanks.
They appear after glibc update. Looks suspicious but nothing seem to be broken atm
kernel is actually 6.1.10-2-rpi-ARTIX-RPI4
system seems stable, but ldconfig segfaults eg
$ sudo ldconfig
Segmentation fault
Downgrading glibc-2.37-2 to glibc-2.36-7 fixes the ldconfig segfault
