after kernel upgrading, kernel module auto loading not working:
https://docs.kernel.org/admin-guide/sysctl/kernel.html#modprobe
root@n242:~# uname -r ; cat /proc/sys/kernel/modprobe
4.18.0-305.3.1.el8_4.x86_64
/sbin/modprobe
root@n67:~# uname -r ; cat /proc/sys/kernel/modprobe
5.14.0-427.20.1.el9_4.x86_64
/usr/sbin/modprobe
fix: echo /sbin/modprobe > /proc/sys/kernel/modprobe
