VMware ESXi 4.0 PSoD Help!

We just bought a Dell PowerEdge 2970 and installed ESXi 4.0 on it. We used VMware Converter to migrate all the VM's off of VMware Server with a Windows Backbone to this new ESXi host. Almost every 48 to 72 hours the host freezes up and gives us the PSoD.

 Attached is a picture of the PSoD with a "PCPU 7 locked up. Failed to ack TLB invalidate." However today we received a "PCPU 8 locked up. Failed to ack TLB invalidate."

Any help here would be nice...

1.I guess one of your physical CPU(s) or one of the cores in either of the CPU has a problem.
2.How old is your Dell PE 2970 BIOS ? Have you updated it recently ?
3.Is this the only ESXi 4.0 Server in your environment ? Do you have spare hardware ?

This is what i thought too just judging by the description.

2.How old is your Dell PE 2970 BIOS ? Have you updated it recently ?

I will have to check to see if there is an update available, this could be an issue and hopefully is. I would hate to have to replace the CPU on a machine that is weeks old.

3.Is this the only ESXi 4.0 Server in your environment ? Do you have spare hardware ?

Yes, this is the only ESXi server. This is a trial run of VMware for my office and the way things are going its not looking so great right now! ;-) I will get back to you on Monday about the BIOS.

Does anyone think that this could be an issue with the type of CPU perhaps? The old box had Intel Quad Core and the new box has AMD' 6 cores...Not sure if that matters in VM world or not. Thoughts?

CPUs of either vendors could fail.
What about BIOS ? Is it updated or is it old ?

The BIOS is up to date with the 4.1.1 from Dell. Any other thoughts?

Here is a thought...How about I update to hypervisor so that it has all the latest patches!?!?!?!?

Stupid me...I did this and the PSOD has gone away.
