Re: driver 275.09.07 causes corruption and hangs w/ gnome3
@MartinKG: I'm sorry I'm the one to tell you this but you are unfortunately barking up the wrong tree. :-( Those errors indicate that something is very wrong with your harddisk (or whatever device is behind /dev/sda in your case). You should check the device for serious defects and if it is your main harddisk, get it replaced asap. Harddisk errors can lead to all sort of trouble- including hangs and freezes, unfortunately.
