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. Best Regards, Huang Ying
