The event registration happens in the PCIBus realize function, however the PCI bus is not 'realized' *at all* for some machines. It appears to be a hidden issue revealed by the above commit. Thanks Mark Cave-Ayland and Leon Alrae for reporting it! For all the series: Reported-by: Leon Alrae Reported-by: Mark Cave-Ayland Patch 1: Increase the timeout for the prom-env-test since I encountered random failures. Patch 2-7: Separate fix for each arch so it will be easier for maintainers to ack.
