Hi, I tried the vanilla kernel, and followed the instructions on the page you linked. However, it fails at creating initrd saying returning an error (file not found) about grub and YaST.
You need to paste the exact error here. Also, have you installed 13.1 from scratch or was it an upgrade from something older? It worked just fine here (bugzilla wraps long lines so I'm adding the log as an attachment). -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
