First I tried the 2.6.24-rc7.bz2 image mentioned at:
http://user-mode-linux.sourceforge.net/
And it worked. Next, using the same rootfs, I checkout 2.6.26-rc7
and generated a UML guest for it. Looking at the
uml/include/config/kernel.release indicated the version of the UML
guest as:
2.6.26-rc4-00103-g1beee8d
It bootup no problem as well.
Next I checkout the 2.6.26 branch (current master), and generated a
UML guest for it. Now the guest have the same version as the host -
2.6.26. But bootup with errors:
EXT3-fs: mounted filesystem with ordered data mode.
VFS: Mounted root (ext3 filesystem) readonly.

Seems similar to that of:

Any fix yet?
