I have a stock kernel (well, gentoo-sources) on the outside, not a SKAS3 patched kernel.

My setup is: Host boxes: - Dual dual-core opteron 265 with 6GB of RAM running 2.6.17-gentoo-r8 - Turion laptop with 2GB of RAM running currently 2.6.20-rc5 (stock) but most recently 2.6.19-ck1 (stock). - Athlon64 3000+ with 1GB of RAM running ck-sources-2.6.19_p2-r3 Notice, no UML related patches on the host boxes. UML Boxes: - usermode-sources-2.6.16-r6 (2.6.16 with genpatches 15 and -bs2) - usermode-sources-2.6.18-r1 (2.6.18 with genpatches 8 and -bb2) - Modified usermode-sources-2.6.14-r6 (2.6.14 with -bs3 and networking patches for work) (this one also runs on 32-bit hosts running various gentoo kernels on workstations at work) All of these run some form of Gentoo inside; not necessarily recent. Each of them runs in both 32 and 64 bit versions. I have also briefly run a UML with a fedora core 2 image, running a usermode-sources-2.6.18 kernel, on the opteron box, but that was only very briefly. That's a 32-bit only UML.
