Works fine here (Debian Sarge, Xen 2.0.1, drbd 0.7, kernel-source 2.6.9). By ''stock'' and ''Fedora''s latest'' I assume you are talking about precompiled binaries, which is probably your problem. Build from source.

Build from source.By stock I mean built from clean sources, without Fedora''s patches. But to clarify, I had a xen-2.0.1 system running drbd 0.7.7, with the same problem. What is your version of drbd? And might it be caused by some different options I have to use to run xen0? (device mapper, network devices...)
