Hi i have the same thing happening .but it does it all the time . some times if i boot up it freeze or if i leave it alone for a while .again no responds to keyboard or mouse the only thing you can do is a reboot.
Well I only experience lock ups while ripping CD's. LMCE is fully working on playing media, and entering inn and out of KDE etc...
I have an other problem as well now! I am loosing access to the media on a NTFS mount, where I have most of my media... But I have ordered a new HDD, that I am gone set up with linux file system, and then transfer my data over the network to my new disk. Well thats the plan anyway
I will rethink the two CD install, thanks for your advise Govo
