PSOD BlueScreen: VERIFY bora/vmkernel/sched/cpusched.c:11152

Products

• VMware vSphere ESXi

Issue/Introduction

Multiple hosts experienced a Purple Screen of Death (PSOD) following an upgrade or system operation. The backtrace from the PSOD indicates a failure in thread scheduling, resulting in the system crash:

 

Environment

ESXi 7.X

Cause

This issue is tied to the SDC driver (scini), which is responsible for certain kernel-level operations. This situation can result in a deadlock, causing the ESXi to crash and trigger the PSOD.

 

Resolution

The PSOD team strongly recommends engaging the hardware vendor for further investigation. This issue is with SDC driver (scini), and its interaction with the kernel, and the hardware vendor should be consulted for further guidance.

For troubleshooting and further assistance, please contact the hardware vendor and provide them with the PSOD logs and memory dump analysis. They can investigate the issue with the scini module to determine whether a firmware or driver update is required to prevent the issue from recurring.

Engaging the vendor will help ensure that the issue is properly addressed and any necessary updates or patches are applied to resolve the underlying cause.
