I'm new to Unraid but I have quite a bit of experience with Linux in general and like most of you, I'm trying to build a NAS/Homelab that has to be as power efficient as possible 🔋. I have the following components: - Gigabyte B760M DS3H AX DDR4 - Intel i5-12400 - 16GB RAM - Corsair CX550 With the above configuration, using a cheap Kingston SSD, Ubuntu Server 24.04 with the amazing `powertop`, I'm able to reach Package C10 and a power draw at the wall of just 8-10w. I followed most of the advices in this blog post, specifically for the internal Realtek RTL8125 2.5GbE Controller which requires a different driver than the one shipped with Ubuntu. Using Unraid tho, the power draw jumps to 15/16w after `powertop --auto-tune` and the Package can only reach C3. From an initial investigation looks like that the "xHCI Host Controller" (The USB controller) is responsible for that and the Unraid USB Flash Drive (usb-device-058f-6387 in the screenshot below, which is the one where the Unraid OS is) prevents the controller to be suspended: As you can see it's the only difference from the Ubuntu Server setup: Does someone have an advice on how can I force the USB to go to sleep? 🙏
