I believe this is due to bug https://bugs.acpica.org/show_bug.cgi?id=1062
I forced an early abort from the infinite loop using the horrible hack: diff --git a/src/acpica/source/components/events/evregion.c b/src/acpica/source/components/events/evregion.c index efaf38b..90e9656 100644 --- a/src/acpica/source/components/events/evregion.c +++ b/src/acpica/source/components/events/evregion.c @@ -529,6 +529,7 @@ AcpiEvDetachRegion( LastObjPtr = &ObjDesc->Region.Next; ObjDesc = ObjDesc->Region.Next; + break; } /* If we get here, the region was not in the handler's region list */ And then I was able to run fwts to completion: ./src/fwts method --dumpfile=AcpiTables.txt - > results.log Attached are my results. It shows that the method test works OK and doesn't fail. So I guess the objects are not being found because ACPICA is getting stuck. ** Bug watch added: bugs.acpica.org/ #1062 https://bugs.acpica.org/show_bug.cgi?id=1062 ** Attachment added: "results.log" https://bugs.launchpad.net/ubuntu/+source/linux-lts-raring/+bug/1255843/+attachment/3928612/+files/results.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1255843 Title: [Lenovo V480] Multiple CRITICAL/HIGH failures in the fwts report To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-lts-raring/+bug/1255843/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
