--- Comment #4 from Stefano Avallone stavallo@unina.it 2011-06-28 10:04:37 --- Well, I re-installed kernel 2.6.39 and even 2.6.38.6, but I still get the same problems. The last times I tried, the system freezed for a few seconds, then the monitor got powered off and I was unable to ssh into the system.
I know that I have provided too few information. I don't remember well, but maybe I started to got these problems without updating any software (though I am not 100% sure). Might it be an hardware problem of the video card?
Any suggestion for possible tests is very appreciated, thanks.
