So .. why are you still using this setup?
Debian uses relatively-new kernel, which is not as widely-tested as
the old 2.6.18 kernel for Xen. Add to it the fact that you're using a
snapshot version, which is even less-tested, then I have to say it's
not really surprising for it to have bugs.

I'd recommend you use a well-tested known-to-work setup. I don't know
which version works best for Debian, but I do know that a RHEL-5.3
domU with kernel 2.6.18-128.1.6.el5xen can read-write lots of data
from nfs just fine (just tested it with a 1G file).

Since the bug seems to be on dom0 kernel, you might want to try using
2.6.18 kernel from xen.org, or try some older xenified debian kernel.
