When I cold-boot the laptop with an empty express card slot and let acpiphp do the
hotplug work, I get same lspci values with one difference. The PME# values are flipping
in opposite direction (ASPM L1 Enabled -> ASPM L0s L1 Enabled on pure hotplug whereas
on the subsequent hotplugs on a cold-booted laptop with a card inserted the changes were
ASPM Disabled -> ASPM L0s L1 Enabled [the original email in this thread]):
Below is the pure acpiphp hotplug behavior for reference with 'pcie_aspm=off' and 'nousb'
for which the PME# game does NOT happen:

The purely acpiphp hotplug data are in Firewire_hotplug_disabled_Media_card_reader_nousb/
subdirectory. Diffing dmesg under Firewire_coldplug_disabled_Media_card_reader_nousb/
and under Firewire_hotplug_disabled_Media_card_reader_nousb/ is left as an exercise for the
reader willing to resolve the
- ASPM L1 Enabled -> ASPM L0s L1 Enabled
+ ASPM Disabled -> ASPM L0s L1 Enabled
underlying issue.
