Environment

VMware vSphere ESXi 7.x

VMware vSphere ESXi 8.x

Cause

Recurring inconsistent boot errors, specifically implicating the vmkusb driver and other system files (though specific errors may vary), strongly suggests a corrupted boot environment rather than a stable hardware or configuration failure. The unstable boot process pointed toward damaged or incorrectly loaded files.

Resolution

1. Revert the ESXi host from the failed state back to the previously stable version using the official reversion method from the below link:

Reverting to a previous version of ESXi

2. Once stable, perform a fresh upgrade to the target version.
