I agree. I don't think blacklisting PNP0A03 is the correct solution. Any ACPI device can have a producer resource. The next time we find a non-PNP0A03 bridge device with a producer resource, we'll just trip over the same problem again. Adam, Len, or Shaohua, can you explain the reason for preferring a blacklist entry? - To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
