Hi, Henrique
Rafael has already pushed a bunch of patches related with power resources.
Can the issue mentioned in this bug be fixed by these patches?
Thanks.

It got rid of the list to (potentially freed) memory, so it fixed PROBLEM-3 for
sure. Which is good, that means the other problems can be fixed

Due to the D3 problem of some devices, PCI will *NOT* place any devices

I agree with the proposal as a good fix for PROBLEM-1, and it will be trivial
to fix some of the other problems later.

No, it is not related. There are many defective PCI devices which cause severe
problems when they are placed in D3 (the most common is that they cannot

Well, nowadays, this report is about the power resources not working, and not
being easily fixed. It is about more than they not being disabled :(

Thanks for the response.
Maybe what you said sounds reasonable. But how can we check whether the ACPI
power resource is used? By traversing the power resource list?

We shouldn't go turning ACPI power states to OFF if the BIOS handled the device
already turned ON (with the power source enabled as well).

It is a bit more basic. The resources are not being attached to all devices
properly, and because of that, someone decided to break things further to avoid
shutting down devices
