Lets try to configure it for a 2-node and see if that triggers the problem. It
can be electrical power drain related - I have caused the power breaker to trip
a couple of times when utilizing that 4-node to its full potential.
The 4-node in Beaverton do not exhibit this problem.
Problem traced down to bad CPU board or bad CPU. Not sure which and is working
on swapping components to determine which is at fault.
Updating the CPLD did not fix it either.
I cannot make this a beta blocker when we only see the issue on one lab system.
IBM needs to continue their work on resolving the HW issues on the x460 in the
back-leveling the BIOS (to 154B) fixed the problem.
The system is currently running the pounder21 test on 1767381 test kernel in a
CLosing BZ as NOTABUG since this was a BIOS issue.
