The root cause is that the Linux kernel lacks a mandatory 10ms delay on the D3cold-to-D0 power state transition path for PCI endpoints, as required by the PCI specification — the delay exists only for D3hot and for bridges. AMD Linux engineer Mario Limonciello traced the issue and submitted a patch adding the missing 10ms delay to the D3cold path in the common PCI driver code, which appears to resolve the problem. ## Full article daily.dev links to this article rather than hosting it.
