When troubleshooting some BIOS code I encounter strange errors about firmware bugs. On closer inspection I found that the Trigger table returned from the firmware was empty but the header looked OK: header_size = 16 table_size = 16 entry_count = 0 When looking at einj.c I found that this header would result in the error I was receiving. I took a quick look at the docs and from what I can tell this is a valid header, yes? I don't know much about ACPI so I might be way off but the attached patch fix the error message for me (however I still can't detect the injected error but that might depend on my detection code or buggy firmware...)
