Original Document Release.

Certain HP ProLiant servers with AMD Opteron (6200-series processors) running a Hypervisor host operating system such as VMware ESXi 5.X or VMware ESX/ESXi 4.X, may intermittently encounter operating system unresponsiveness, a kernel panic or VMware Purple Screen (PSOD). If this occurs, one of the following error messages may be displayed:

CPUx tried to re-acquire lock CpuSchedCore. X

Page Fault # PF Exception 14 in CpuSchedVcpuSwitch()

System unresponsiveness, a kernel panic, or VMware ESXi Purple Screen (PSOD) may occur during moderate to heavy CPU stress or when network stress occurs between Virtual Machines (VMs) while the system is configured with a supported System ROM version dated 12/08/2012 or 12/09/2012.


Note: This issue may randomly occur on servers with AMD Opteron 6200-series processors running VMware ESXi 5.X or ESX/ESXi 4.X, but there is a potential for it to occur while running other Hypervisor operating systems. The affected servers are listed in the Scope of this advisory.


The following is an example of a VMware ESX/ESXi 4.1 Purple Screen with the following error message displayed:

Page Fault # PF Exception 14 in CpuSchedVcpuSwitch()

VMware ESX/ESXi 4.X:
This error message may be encountered on the affected servers that include AMD Opteron 6200-series processors running VMware ESX/ESXi 4.1. The actual PSOD message displayed is dependent on the failure mode:

 

VMware ESXi 5.X:
The following is an example of a PSOD screenshot that may be encountered on a server running VMware ESXi 5.X; the actual PSOD message displayed is dependent on the failure mode:

The following is an example of entries that may be displayed in the VMkernel-zdump.log file when this problem occurs:
