Red Hat Summit9장. Keeping kernel panic parameters disabled in virtualized environments
When configuring a Virtual Machine in Red Hat Enterprise Linux 10, you must not enable the softlockup_panic and nmi_watchdog kernel parameters. This results into Virtual Machine might suffer from a spurious soft lockup that should not require a kernel panic.
The reasons behind this advice are as follows.

A soft lockup is a situation usually caused by a bug, when a task is executing in kernel space on a CPU without rescheduling. The task also does not allow any other task to execute on that particular CPU. As a result, a warning is displayed to a user through the system console. This problem is also referred to as the soft lockup firing.
