We have seen an internal document that advises that the HP DL360 G5, DL380 G5 and Dell PowerEdge 1950 and 2950 models have some serious flaws and they need to get updated.

Things are serious as "Intel has recently communicated a flaw in their dual and quad core processor offerings which may cause a random circuit timing issue. Intel has observed the issue only under extreme internal validation testing."

The good thing is that there where no reported incidents, but the affected system might generate a hardware fault and then BSOD under Windows. The hardware fault may not result in error conditions under Linux.

The microcode patch that can fix this issue will be made available via a recommended BIOS update from our server OEMs.

The BIOS that can fix this issue was suppose to go out in late April, but we are not sure what happened there.

The following systems are affected:

 HP Proliant DL369 G5
 HP Proliant DL380 G5
 Dell PowerEdge 1950
 Dell PowerEdge 2950

If you have one of them, call your tech guy and ask him to fix it yesterday.
