Dear all, there is a guy who submitted a bug related to the Debian linux-patch-skas package: he affirmed to encouter problem in working with the host kernel once compiled and patched SKAS. The host kernel release is reported in the subject. At the end of his analysis, he noticed this problem occurred only with AMD Athlon 2200+, then with -k7 CPU type [*]: in particular with 2.6.18-5 compiled for K7 and patched with debian's linux-patch-skas (the same of Blaisorblade's). You can get details of the thread (a few mails) at the following link: http://lists.alioth.debian.org/pipermail/pkg-uml-pkgs/2006-November/000438.= html Cheers SteX [*] http://lists.alioth.debian.org/pipermail/pkg-uml-pkgs/2006-November/000481.= html ----- Forwarded message from Stefano Melchior <ste...@op...= > ----- Date: Fri, 24 Nov 2006 14:54:20 +0100 =46rom: Stefano Melchior <ste...@op...> To: "Peder Chr.

To affirm it I need to investigate a bit more. Did you test the just-compiled kernel (with SKAS patch) with an pre-build uml instance to check if it works? If I remember well you can find here, in http://uml.nagafix.co.uk/, some uml instances. Anyway what is your rootstrap.conf configuration?
