Noticed this myself, Got a temp 500 series board and 3600, USBC has issues and "can" cause slow boots and odd bugs.

I have a USB SD card reader that my X99 system won't boot with when it is connected. Nothing to do with this specific AMD USB problem, but it's just one of the silly issues that I have to deal with ATM.

When I had my X99 rig it would randomly reboot on its own if I used Corsairs AX860i power supply, PSU was fine but there was an issue with OCP being falsely triggered by something in the bios, This is why I wish vendors would actually test their products properly instead of just sending them out.

is this related to the mouse/keybaord lag when c-states are enabled?

I think it is related but not solved by disabling C-States, For example, Many Razer keyboard owners have noticed an issue specifically with 500 series AMD boards, Issues with slow boot and various hitching issues, Razer even said on their forums they have the same issue in their offices with their own employees who have AMD rigs and are looking into a fix.
