OS boot phase with the below error: BUG: soft lockup - CPU#1 stuck for 67s! [swapper:1]
¶ Cause
The error is more of a warning regarding a kernel lookup which is locking when something went wrong.
It points toward CPU being unresponsive to a softlockup timer (interrupt) within the timer window.
A 'softlockup' is defined as a bug that causes the kernel to loop in kernel mode for more than 20 seconds without giving other tasks a chance to run.
Softlockup can occur is when the machine goes into a loop with interrupts turned off.
This commonly happens if a device driver uses spinlocks improperly, but this error also could be caused by faulted hardware.

Diagnosing The Problem
