One of the two reports in bug 9320 seems to be the same problem although the other doesn't seem to be. So, it seems we'll have to check that both primary and secondary slots are empty and skip _GTM if so. :-( Also, right, there's no need to fail suspend on _GTM failure whatever the error is. That was me being anal again. Will incorporate both into the ACPI fixes patchset. Thanks. -- tejun
