Hi all, After an electric breaking, my server (Centos 5.2 x86_64 with all updates) can not boot. The error message on screen is:

Anyone could tell me how to fix this please ! Help !
you have a hardware problem. something fried on the motherboard, possibly the ram, maybe something else.. if the server is on some sort of service contract or warranty, call the hardware or support vendor. if not, find someone skilled at troubleshooting x86_64 server hardware.
I believe the Machine Check Exception: 7 Bank 4 does seem to indicate its a memory ECC issue with DIMM bank 4 on CPU 1 (I'm guessing this is an Opteron system?)
you might try booting a memtest86 CD and seeing if that runs.
