[Back now]

My git bisect ended up to this commit:

  9d573d19547b ("PCI: pciehp: Detect device replacement during system sleep")

Adding Lukas who is the expert.

My steps to reproduce on Intel Meteor Lake based reference system are:

1. Boot the system up, nothing connected.
2. Once up, connect Thunderbolt 4 dock and Thunderbolt 3 NVMe in a chain:

  [Meteor Lake host] <--> [TB 4 dock] <--> [TB 3 NVMe]

3. Authorize PCIe tunnels (whatever your distro provides, my buildroot just
    has the debugging tools so running 'tbauth -r 301')

4. Check that the PCIe topology matches the expected (lspci)

5. Enter s2idle:

  # rtcwake -s 30 -mmem

6. Once it is suspended, unplug the cable between the host and the dock.

7. Wait for the resume to happen.

Expectation: The system wakes up fine, notices that the TB and PCIe devices
are gone, stays responsive and usable.

Actual result: Resume never completes.

I added "no_console_suspend" to the command line and the did sysrq-w to
get list of blocked tasks. I've attached it just in case it is needed.

If I revert the above commit the issue is gone. Now I'm not sure if this is
exactly the same issue that you are seeing but nevertheless this is kind of
normal use case so definitely something we should get fixed.

Lukas, if you need any more information let me know. I can reproduce this
easily.
