VMware ESX 4.0 Error: Unspecified 1 Critical Int: Bus Uncorrectable error

Server Model: IBM System x3650 -[797941U]

This error seemingly at random.  Just was logged into vSphere and running updates on a different server when this popped up.  All the VMs on this host are still working, all the front panel lights of this particular server are all green and show no alerts.  Any ideas what is is caused by or related to and how it can be fixed?

These type of errors indicate a NMI event. (Non-Maskable Interrupt).


It can sometimes indicate a hardware fault or condition.

I've seen them only on IBM "Blue" kit! If the problem exists, escalate to IBM to investigate.

You definitely want to get your server updated get yourself the latest UEFI drivers, and for the server you want to make sure in your BIOS you do not have any errors that can stop post.

In addition you want to ensure that your BIOS is using the Physical CPU configuration and PStates Enabled as these settings are critical for correct licensing and optimal power function.

Went away on its own, strange; but there are driver packages to download from IBM and VMware.  I'll get to installing these.

Problem went away on its own.  Although the advice to download drivers is good, it technically didn't directly fix our problem.
