I thought about that last night as well and we are having the same issue
with a system using Ubuntu 7.10.  I did noticed though 7.04, 7.10, 8.04
are all using 2.2.13 but different patches. 7.10 uses the 2.2.13-11
while 8.10 uses the 2.2.13-13.  I am thinking of trying 8.10 to see if
it works.. if not.. sadly I am wondering if we will have to move the
system over to a full Debian stable/testing?  I would not be happy to
build a Debian testing system to find out we have the same issue.  Would
this be a Ubuntu related issue with their patches?  Has anyone else have
had the same issue without using Ubuntu?
