CentOS - Feb 2009 - After electric breaking: HARDWARE ERROR Kernel panic

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:

-----------------------------------------------------------------------------------------------------------
Memory for crash kernel (0x0 to 0x0) notwithin permissible range
<0>
HARDWARE ERROR
CPU 1: Machine Check Exception:   7 Bank 4: ....
RIP 10:<.....>
TSC 133eab63c9 ADDR 24fe3d028
This is not a software problem!
Run through mcelog --ascii to decode and contact your hardware vendot
Kernel panic - not syncing: Uncorrected machine check
-------------------------------------------------------------------------

Anyone could tell me how to fix this please ! Help !

Thank you

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.

I doubt a warranty will cover electrical damage, but you can ask.....
 An insurance policy is more likely to cover this.  :-)    Run
Diagnostics on the RAM (which is the reported error) and your
motherboard.  The PSU may also be damaged. Run Diagnostics on the hard
drives, after you get it up and running.

Fixed ! I boot with old kernel and reboot again with new kernel. That''s
ok now

Thanks
