After that it boots up normally, and reboots properly provided that mains power is never disconnected.

So Intel still needs to fix this.
I get a similar.... restore power, boot and then my rig shutsdown and reboots itself again into no screen etc... so I soft reboot and all fires up good.
No 'Post Failed messages', or anything like that

I always thought the X48 was a "golden sample" type X38... same components, same software, same drivers, same everything... different logo printsecreened on the board.
