The sysace device can very easily get wedged up and the current driver
doesn't handle it very gracefully.  Usually the problem is seen if the
board gets reset mid-transaction (which looks a little bid different
from what you've got here; but is probably related).  The problem
should be solvable, but I haven't been able to spend any time working
on it recently.  You'll need to dig into the sysace documentation and
figure out what the status/ctrl registers mean to find out why it is
wedged up and see if you can teach the driver to work around it.
