    Note: The preceding log excerpts are only examples. Date, time, and environmental variables may vary depending on your environment.


Environment

VMware vSphere ESXi 7.0.0

Cause

This issue occurs as sometimes, Hardware Parity attentions (i.e. TCM, XCM) are hit with SRIOV+RoCE configuration which leads to engine reset recovery. 

In this driver version, during engine reset recovery with VFs, the driver can go to bad state and cause a PSOD as VF driver is not aware of the engine reset.

Resolution

To resolve this issue, ensure the RoCE function is disabled when SRIOV function is in use.

Note: RoCE function is disabled in qedentv by default. VMware recommends to not set "enable_roce=1" in the qedentv module parameter when SRIOV function is in use.
