This error indicates a class of bug, not a specific bug. The Xen kernel
flavour is unfortunately very unstable in lenny, and noone seems to be
able to fix it. Note that you can run the 686-bigmem and amd64 kernels as
domU under Xen, and these appear to be much more stable.
drbd is a separate module not supported by the kernel team. You can
contact the drbd maintainers at
<debian-ha-maintainers@lists.alioth.debian.org>.

That is not the problem; the problem, is how can *we* reproduce this
error and track it down. We don't have an answer to that.

Yes, see <http://bugs.debian.org/src:linux-2.6>.

Some causes have been fixed, others not.

Sorry, etch security support has ended.
