This means:

The generic hardware error source with ID 1 is notified by poll, that
is, Linux should poll the specified address to check whether there is
hardware error report from hardware.  But the poll interval specified by
firmware is "0".  I think this should be a firmware error, and disabled
it.  I think maybe you can contact firmware vendor to fix this.
