But I found something interesting which makes difference. If I disabled the "Wake on Dell USB-C dock" feature in BIOS setting, the problem will be gone. That matches the finding in the description, the power state change failure will always happens then the HC died after. I'll ask more detail about this feature. But also need suggestion about how we should handle this unexpected wakeup for the xhci_hcd. --=20 You may reply to this email to add a comment.
