TL;DR: change kernel to ubuntu's `linux-image-6.8.0-32-generic` seems fix the soft lockup
NPS is set to 2
The VM is a k8s worker node with high tmpfs usage. Lockups seem to occur quite frequently, approximately every 6 hours.
I tried disabling numa_balancing and ksmtuned, but it didn't seem to have any effect.
I then tried installing the ubuntu 24.04 kernel. and the VM seems pretty happy (with ksmtuned on and numa_balancing on)
