Hello, I have been using Fedora (KDE spin) for quite some time. There was absolutely no problem till Fedora 14. But now when I try to install Fedora 15, the live CD does not boot. I have tried Gnome Live CD and also the DVD. I even tried the pre-upgrade procedure. All give the same result. The CD/DVD begins to boot, some text messages appear and finally the CD/DVD activity stops with the line [ 1.319497] [<c040377e>] kernel_thread_helper+0*6*0*10. My machine is Lenovo C 200 (Intel Atom D410 dual core processor). I am not a computer expert. But I am moderately familiar with Linux because I have been using it for more than 12 years. How do I overcome this problem? - Vijayan -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
