Guys, I'm trying to start uml with website fedora fs.
I downloaded 2.6.26 source and build without problems. But when I
start I have segmentation fault error.
I'm a bit confused about these messages:
console [mc-1] enabled
ubda: unknown partition table
EXT3-fs: mounted filesystem with ordered data mode.
VFS: Mounted root (ext3 filesystem) readonly.
My fs was mounted ok? What is ubda partition error?
Anyone have some suggestion? Log messages below.
My host is: Linux ubuntu 2.6.24-16-generic #1 SMP Thu Apr 10 13:23:42
UTC 2008 i686 GNU/Linux
Thank you,
- Roberto
