The PCI subsystem updates also include power management fixes to prevent runtime suspend during device initialization, eliminate redundant D3hot-to-D3cold transition delays, fix potential P2PDMA hangs during device removal, and add support for PCIe M.2 connectors in the power sequencing subsystem along with a new ASpeed root complex Device Tree driver. ## Full article daily.dev links to this article rather than hosting it.
