https://bugzilla.novell.com/show_bug.cgi?id=732471 https://bugzilla.novell.com/show_bug.cgi?id=732471#c2 --- Comment #2 from Petr Vandrovec <vandrove@vc.cvut.cz> 2011-11-24 00:56:53 UTC --- Regression is caused by this upstream commit. It causes acpiphp to not be loaded whenever OS acquires PCIe hotplug control from the platform - even if there are non-PCIe bridges in the system. It makes PCI devices hotplug impossible in all VMware's virtual machines. commit 0d52f54e2ef64c189dedc332e680b2eb4a34590a Author: Rafael J. Wysocki <rjw@sisk.pl> Date: Sat Oct 22 00:43:38 2011 +0200 PCI / ACPI: Make acpiphp ignore root bridges using PCIe native hotplug If the kernel has requested control of the PCIe native hotplug feature for a given root complex, the acpiphp driver should not try to handle that root complex and it should leave it to pciehp. Failing to do so causes problems to happen if acpiphp is loaded before pciehp on such systems. To address this issue make find_root_bridges() ignore PCIe root complexes with PCIe native hotplug enabled and make add_bridge() return error code if PCIe native hotplug is enabled for the given root port. This causes acpiphp to refuse to load if PCIe native hotplug is enabled for all complexes and to refuse binding to the root complexes with PCIe native hotplug is enabled.
