Hi all, after openSUSE changed its kernel config to statically build in acpiphp and pciehp, my ExpressCard slot does not work anymore. The workaround is to disable acpiphp with acpiphp.disable=1 To be honest, I cannot say if it ever worked with both drivers loaded, since I always had to load pciehp manually to get the slot working. I don't think I ever tried acpiphp before. If necessary, I can either build a kernel with both drivers modularized or just boot an old kernel from before the config change. I did diff both dmesg outputs and the only differences I can see are: -kernel: acpiphp: ACPI Hot Plug PCI Controller Driver version: 0.5 +kernel: acpiphp: ACPI Hot Plug PCI Controller Driver version: 0.5, disabled by user; please report a bug @@ -401,7 +400,6 @@ kernel: pci 0000:03:00.0: PME# supported from D0 D3hot D3cold kernel: pci 0000:00:1c.1: PCI bridge to [bus 03] kernel: pci 0000:00:1c.1: bridge window [mem 0xf2500000-0xf25fffff] -kernel: acpiphp: Slot [1] registered kernel: pci 0000:00:1c.3: PCI bridge to [bus 05-0c] kernel: pci 0000:00:1c.3: bridge window [io 0x2000-0x2fff] kernel: pci 0000:00:1c.3: bridge window [mem 0xf0000000-0xf1ffffff] @@ -585,8 +583,7 @@ kernel: pciehp 0000:00:1c.1:pcie04: HPC vendor_id 8086 device_id 2942 ss_vid 17aa ss_did 20f3 kernel: pciehp 0000:00:1c.1:pcie04: service driver pciehp loaded kernel: pciehp 0000:00:1c.3:pcie04: HPC vendor_id 8086 device_id 2946 ss_vid 17aa ss_did 20f3 -kernel: pciehp 0000:00:1c.3:pcie04: pci_hp_register failed with error -16 -kernel: pciehp 0000:00:1c.3:pcie04: Slot already registered by another hotplug driver +kernel: pciehp 0000:00:1c.3:pcie04: service driver pciehp loaded kernel: pciehp: PCI Express Hot Plug Controller Driver version: 0.4 kernel: intel_idle: does not run on family 6 model 23 kernel: GHES: HEST is not enabled! The other changes are * kernel command line (obviously) * timing related (small difference in cpu freq / jiffies) Greg told me to report the issue here, so I'm doing that :-) If you need more information (would a complete dmesg of both cases be useful?), just let me know.
