Unfortunately no solution. I think it's Unraid bug, perhaps something about Linux kernel that they are using or its configuration.

Resurrecting this topic in case someone can help. I have a lot of PCIE devices with disabled ASPM despite existing capability. ASPM is on in BIOS and forced on boot: root@Tower:~# dmesg | grep -i aspm [ 0.000000] Command line: BOOT_IMAGE=/bzimage initrd=/bzroot pcie_aspm=force [ 0.041209] Kernel command line: BOOT_IMAGE=/bzimage initrd=/bzroot pcie_aspm=force [ 0.041237] PCIe ASPM is forcibly enabled [ 0.404889] acpi PNP0A08:00: _OSC: OS supports [ExtendedConfig ASPM ClockPM Segments MSI HPX-Type3]But despite all that Unraid is not enabling ASPM on capable devices: root@Tower:~# lspci -vv | awk '/ASPM/{print $0}' RS= | grep --color -P '(^[a-z0-9:.]+|ASPM )' 00:01.1 PCI bridge: Advanced Micro Devices, Inc.

Spinning down 5 HDDs reduces it a little but not much. I have "power efficient" policy in Unraid settings. I ran "echo -n powersave > /sys/module/pcie_aspm/parameters/policy" to no effect.
