New findings from a controlled reboot on 2026-09-14. Automatic enumeration again left the AQC113 unavailable, while guarded removal and rescan of the JHL7440 subtree restored the in-tree Atlantic driver and a 10 Gb/s link. The identical requester-69:00.0 AER resumed approximately 0.57 seconds after xHCI initialization and before Ethernet linked, demonstrating that the PCI resource-allocation recovery and persistent xHCI transaction fault are distinct outcomes.
