Can you give me any pointer how to "call the ACPI _PR3 method"?
i already install acpi_call, but have no idea how to use it
The pci core should be doing it for you since runtime pm support was added to pcie ports: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i... https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i...
Does adding: pcie_port_pm=force to the kernel command line in grub help?
