Ok. I've not been able to reliably reproduce the problem on any other
machine. So I've done the following - hope this is sufficient for you:

Taken the multipath-tools*.tar.gz and extracted it on another etch machine.
Built it with fakeroot ./debian/rules binary

Copied the kpartx deb and multipath-tools deb to feynman and installed
them.

Then rerun my test which seems to work correctly. I've not seen any
failures.

I haven't done anything with devmapper. Not sure if that matters or not
for you but I don't really want to start replacing existing packages on
this machine even temporarily and I assume that will replace
libdevmapper.

Tim.
