I've observed that the VM running Kali has been running continuously on the Beelink U59 Pro Proxmox host and I find that it is running version 6.3.7 of the Linux kernel. I further observe that the Ubuntu 22.04 VM that locks up is running version 5.15 of the kernel, so I am wondering whether upgrading the kernal of the Ubuntu VM to 6.x (instructions to upgrade to 6.2 are here) will address the problem? #
