more warm boot issue assessments...
Although this is was a review of P5N32-SLI, it was interesting to note nevertheless:

"Unfortunately, getting the system booted was not always that easy. In many cases, booting up the P5N32-SLI resulted in a blank monitor screen and we had to manually shut down the board using the kill-switch on the power supply. Originally, we thought this might have been a heat-related issue, as the system typically would not reboot after running benchmarks and the like. After checking fans and airflow, we were convinced that the setup, at least, was not at fault. We also noticed that the next boot after using the PSU kill-switch, would invariably halt during POST with the message that "overclocking failed or overvoltage failed". The problem with this is that in just about every case, we were neither overclocking nor overvolting any of the components. Investigating the issue, we found that in the Hardware Monitoring section of the BIOS, that the CPU was consistently undervolted, usually by a solid volt off of the expected value. That is, even if we raised the voltage elsewhere, the VCORE Voltage would be one volt lower. We managed to gain a bit of stability by manually raising the CPU voltage, but still found that the system became unresponsive from time to time."
I might bust out an RTA and monitor the CPU voltage values during operation and after a reboot to see what it is outputting to the CPU...
