I assume this happens on hot-adds, i.e., you boot the kernel, then connect a USB4 dock, then connect the TBT3/USB4 storage device to the dock? Would you be able to attach the complete dmesgs log from working and failing kernels? The ideal would be from d3fcd7360338 ("PCI: Fix runtime PM race with PME polling"), which fails, and 5cd903bce9dd ("PCI/VPD: Add runtime power management to sysfs interface"), which presumably works. But v6.7 and v6.5 is OK too. Also the output of "sudo lspci -vv", which I assume doesn't depend on which kernel you're running.

TBT3/USB4 storage device can be authorized, the disk drive doesn’t show up. Issue reproduce sequence: Connect USB4 dock to host → Connect TBT3/USB4 storage device to dock DFP TBT3 port → TBT3/USB4 storage device disk driver can’t show up. The issue was observed in the latest mainline kernel 6.7.
