Your PCI/PM v2 series and the Alpine Ridge quirk were applied as well. The full report is in reply to the series: https://lore.kernel.org/all/20260930141914.6678-1-fbeltranmillalen@gmail.com/ Stock 7.2.5: with both Thunderbolt xHCIs (8086:15d4 at 07:00.0 and 7d:00.0) runtime-suspended, plugging a USB 3 stick into any USB-C port produced no kernel messages at all. With power/control=on, it enumerated at SuperSpeed immediately. With this patch, _OSC reads "OS assumes control of [PCIeHotplug SHPCHotplug PME AER PCIeCapability LTR DPC]". With both controllers left at power/control=auto, the same stick enumerated at SuperSpeed within about 1 s, and 7d:00.0 runtime-resumed on its own. A later run gave the same result: about 1 s when plugged in before a lid-close S3, and about 3 s for a replug about 2 min after resume, still with power/control=auto. The patches were tested together, not bisected. This is the result that maps most directly onto this one patch. Tested-by: Darrell Gum
