Reading Time: 3 minutes Seems that there are still some issues with vSphere 6.5, with a possible PSOD (Purple Screen Of the Death) after upgrade to 6.5U1 on ESXi hosts using 10 Gbps NICs. The VMware KB 2151749 describe this issue and explains that this occurs because Netqueue commit phase abruptly stop due to the failure of hardware activation of a Rx queue. As a result, Internal data-structure of the Netqueue layer’s could go out of sync with the device and cause PSOD.
