Looks to me it is already in 3.10-rc4 which I tested now. No, I still do see
same problem like before: a hotremoval of NEC-based xHCI express card is detected
on every second eject. But, sometimes it seems it is only delayed by some 25-30
seconds. Would have to do more testing. However, there are some *new* kmemleaks
reported by kernel related to acpiphpp bu xhci_hcd. That could a hint why
the hotremoval sometimes proceeds delayed but sometimes maybe not at all or at
least not *immediately* like for any other device?
However, the stale sysfs entries for partially removed device SiI3132 (sata_sil24
driver) are NOT appearing anymore, good. That used to be associated with
'sata_sil24: IRQ status == 0xffffffff, PCI fault or device removal?' line.
Now, I see under 3.10-rc4 the extra message about 'ACPI: Device does not support D3cold'.
would be nice if it said what device is it talking about? About upstream root port
or about my end device (express card)? Is it related by pcie_aspm= kernel
commandline option? If yes, please include the relevant info the message text.
referring to this being affected by the particular value. At the moment I used:
pcie_aspm=off

So, in my eyes the "stale pci info" issue is fixed in 3.10-rc4 at least under acpiphp and pcie_aspm=off.

I opened a bug https://bugzilla.kernel.org/show_bug.cgi?id=59411 .
I wanted to report individual tests but as overnight kernel reported
kmemleaks with interesting stacktraces I took the lazy approach and
uploaded the kmemleaks file and dmesg from the morning without further
splitting the stuff. However, I have step-by-step collected data for
everything in the dmesg since bootup, sadly except the very last
hotremoval. But hope that is not a big loss.
;-)
The SiI3132 card handled by sata_sil24 is treated differently:

I think the eSATA card hotremoval leaves acpiphp in a broken state.
That breaks in turn the NEC-based xHCI card hotplug removal detection while
NOT VIA-based FireWire card which can somehow overcome that.
What one can see in logs that xhci_hcd started to complain:
Hotinsert+removal of a firewire card, note "PME# disabled" line.

A following hotinsert+removal of a SiI3132 card, note "nothing about PME# logged" by pci core. Why?
Is this related to my pcie_aspm=off?
