Subject: 3.10.9 Crash

Hi all, 
I'm remotely managing a 3.10.9 server and this morning I found it locked.
The only data I could gather is a screenshot (thru AMT interface).
I've ran it thru gocr and this is the result (some char got garbled but the 
bulk is ok).
The machine is pretty new and stable, nothin like this happened with previous 
3.10.X

Attached you can find .config file.
If you need more information just let me know (just CC: me as I'm not 
subscribed ATM)
