The following panic happened using uml 2.6.11 with the bs3 patch with the Debian-3.0r0.ext3 image. The host is Fedora core 3 without the skas patch. We're trying to get a stable UML up for running untrusted Lnux guest code, for purposes of creating a system that's planetlab-like in some ways, as an extension to DonutLab <http://www.hpl.hp.com/techreports/2005/HPL-2005-5.html>. For now, our focus is on bringing a proof-of-concept up quickly. For now, we need stability much more than performance. Any suggestions would be appreciated. Thanks.
