RTS525A PCI Express Card Reader +-1c.4-[02-6b]----00.0-[03-6b]--+-00.0-[04]----00.0 Intel Corporation JHL7540 Thunderbolt 3 NHI [Titan Ridge 4C 2018] | +-01.0-[05-37]-- | +-02.0-[38]----00.0 Intel Corporation JHL7540 Thunderbolt 3 USB Controller [Titan Ridge 4C 2018] | \-04.0-[39-6b]-- I disabled the aspm by assign 0 individually to /sys/devices/pci0000:00/0000:00:1c.4/0000:02:00.0/0000:03:02.0/0000:38:00.0/link/l1_aspm and /sys/devices/pci0000:00/0000:00:1c.4/0000:02:00.0/link/l1_2_aspm /sys/devices/pci0000:00/0000:00:1c.4/0000:02:00.0/link/l1_1_aspm /sys/devices/pci0000:00/0000:00:1c.4/0000:02:00.0/link/l1_aspm The same problem happens. 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. -- You may reply to this email to add a comment.
