Default Bug#449024: Voltage spike

Today I have caught another oops. Now it happened with the 2.6.24 based
kernel. I think I have found the root cause of the problem. It seems to be
because of voltage spikes. I don't know if it is a bad power unit, or non-ECC
memory module (I will give another memory check), but this oops happened after
the voltage spike. Here is the log snippets:
