Hi, On a 8 Gbytes server installed with Xen from the GNU/Linux Debian distribution (linux-image-2.6.18-4-xen-686 2.6.18.dfsg.1-11), I have the attached kernel panic when running xen-create-image. In fact I have the same kernel panic when I create the image on a different machine and simply copy the files over an SSH session. The exact same machine with only 2 Gbytes of memory does not crash. Let me know if you need any other information. Thanks. -- Marc Petit-Huguenin Home: marc@petit-huguenin.org Work: marc@8x8.com _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

But if you think that this is still a possibility, I''ll run memtest.

I would recommend building a 2.6.18 kernel from xen-unstable.hg repository, or at least rebuilding your Debian dom0 kernel with the file arch/i386/kernel/swiotlb-xen.c replaced with the version from the xen-unstable.hg repository (or if that doesn''t compile, take the version of the function __sync_single() and copy that into Debian''s swiotlb-xen.c). -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

I will open a bug in Debian soon.
