System Freezing -Again

[Derek Ragona]

A freeze like you describe, no logging sounds like a hardware problem.  You 
didn't include a current dmesg or other system inventory.  You may have 
shared irq's causing the problem, or a power supply, or a management board.

Those are the three things I would look at.
