In more recent kernels (i.e. linux-meta-aws/azure 5.13) I can see messages like this: " watchdog: BUG: soft lockup - CPU#3 stuck for 238s!" that seems to indicate the kernel is not giving back control to the userspace/systemd.
Also a message about a missing autofs4 module, that might be related: "systemd[1]: Failed to find module 'autofs4'"
