You can disable Failsafe Watchdog option in BIOS. That will solve the issue temporally.
Could you please tell me the exact model number of your power supply?
What configuration do you have on the hard drives? As a RAID? if you do What RAID are you using?
You said that you upgraded to the "latest BIOS" what latest bios version is that?
Thank you for your replies.
Unfortunately I didn't saw the LAN problems with the latest BIOS version 8322 and I installed it. Now I have a 10 MB LAN interface .
In this new BIOS version don't exist C1E option but I have made some tests and I found that if I disable Performance -> Failsafe Watchdog the system don't reboot and hang after message machine restart appears (POST code 21 - MRC entry point). If I enable Failsafe Watchdog the system reeboots, but after that appear the message The system BIOS has detected unsuccessful POST attempt(s)... (POST code 69).
I also tried with only 4 GB of memory but no positive results.
Power supply is Spire Jewel SP-ATX-750WTN-PFC.
I have one software RAID1 with 2x 750GB HDD WD7500AADS and one software RAID5 with 3x 150GB HDD WD1500HLFS.

3878 BIOS don't work at all.
It seems that DP55KG motherboard and Linux are incompatible for the moment. Please see:
Until a new BIOS version or a new Linux kernel will appear... do not reboot :D. Or change the motherboard.
This issue seems to be solved for me with the last BIOS update: 5936
I also had an issue with the Network Card not being properly detected by Linux upon startup.
This was also solved with the BIOS update.
I recently bought one of the last remaining models of this board to replace a poorly made ASUS board, and I am glad that Intel solved these problems with BIOS updates.
Keep up the Good work, Intel
