Created attachment 103701 [details] 20130606.tar.gz I found out pcie_aspm=off breaks pciehp on Dell Vostro 3550 (unlike pcie_aspm=compat). Sidenote: It is sad that to have working acpiphp I need pcie_aspm=off and that is how I got trapped here in kernels above 3.5. I tested pciehp under 3.10-rc4 now with 3 different express cards (eSATA SiI3128), NEC USB3.0 card, FireWire VIA chip card. None of them gets detected upon hotplug under pcie_aspm=off. Sidenote 2: Some of them work under acpiphp while some not. I speculated already on the linux-pci list that that is related to their different PME# capabilities. Why they are all broken under pciehp pcie_aspm=off is likely not relevant in this bug report, but bear that in mind just in case. I will upload the following subdir structure: 20130606/3.10-rc4_pciehp_pcie_aspm=compat/ 20130606/3.10-rc4_pciehp_pcie_aspm=off/
