The behavior I'm seeing in jaguar's reports is difficult to characterize
as anything except a seriously broken machine (see the followup message
with further details).  It may be that there is some
not-obviously-broken-hardware case that we need to deal with, but I have
not seen evidence of it yet.  Can you reproduce your test case with CVS
HEAD and send the log messages?
