Hello! I've just upgraded my kernel up to the 2.6.24-gentoo-r2 release, patching it with the skas4 patch successfully. Once I try to run UML, the first bad thing is that it still starts in skas0 mode!!! But I can't run UML too. The filesystem image has been built using debootstrap and it is a 64bit version distribution. It worked with previous versions of host kernels. I also tried with a nagafix.co.uk filesystem image, but I got the same problem.
I'm running UML as root at the moment.
