Under xen, either stock xen-2.0.1+linux-2.6.9 or Fedora's latest (2.6.10-1.1109_FC4), drdb (<http://www.drbd.org/>),as soon as I try to write to one of its devices, causes "Badness" in the kernel and, ultimately, a spontaneous reboot. Under non-xen 2.6.10-1.1109_FC4 and 2.6.9-1.678_FC3, drbd works fine.

It works fine without xen, but fails under xen. Could xen be catching a bug on drbd, or is it a bug caused by xen's paches?
