From broken dmesg (https://bugzilla.kernel.org/attachment.cgi?id=39092): pci 0000:00:00.0: reg 10: [mem 0xf0000000-0xf7ffffff pref] pci 0000:00:1f.1: reg 24: [mem 0x00000000-0x000003ff] pci 0000:00:1e.0: PCI bridge to [bus 02-02] (subtractive decode) pci 0000:00:1e.0: bridge window [mem 0xef000000-0xfbffffff] pci 0000:00:00.0: address space collision: [mem 0xf0000000-0xf7ffffff pref] conflicts with PCI Bus 0000:02 [mem 0xef000000-0xfbffffff] pci 0000:00:1f.1: BAR 5: assigned [mem 0xc0000000-0xc00003ff] agpgart-intel 0000:00:00.0: device not available (can't reserve [mem 0x00000000-0x07ffffff pref]) The conflict between the AGP 00:00.0 BAR 0 and the 00:1e.0 bridge window looks real, so reassigning the AGP BAR looks like the right thing to do. We assign 00:1f.1 BAR 5 in the pcibios_assign_resources() path, and I think we would assign the AGP BAR there, too, except that the class code of 00:00.0 is probably 0x000600 (PCI_CLASS_BRIDGE_HOST), and we explicitly ignore host bridges in __dev_sort_resources(), so it's up to the driver to catch this and assign it explicitly before calling pci_enable_device(). That's kind of ugly because it's an exception to the normal "call pci_enable_device() first" rule, and it leads to bogus "conflicts" like this: pnp 00:0d: disabling [mem 0x00000000-0x0009ffff] because it overlaps 0000:00:00.0 BAR 0 [mem 0x00000000-0x07ffffff pref] but I think we're stuck with it for now, and the simplest solution is to just revert 96576a9e1a. Here's the old commit that made us ignore host bridge BARs: http://git.kernel.org/?p=linux/kernel/git/torvalds/old-2.6-bkcvs.git;a=commitdiff;h=1d... 2004/12/17 13:44:31-08:00 macro [PATCH] PCI: Don't touch BARs of host bridges BARs of host bridges often have special meaning and AFAIK are best left to be setup by the firmware or system-specific startup code and kept intact by the generic resource handler. For example a couple of host bridges ...

I'd be thinking that kworker going wonky is something for Tejun to have a look at.. Anyway, is it still relevant for current kernels? --
Hello, It looks like the work is scheduled in loop, so the kworker acting out seems to be the symptom of the problem not the cause. Looks like Rafael already has a proper fix on mind, so... Thanks. -- tejun --
Rather, something that _might_ work. I'm quite confident that this is a BIOS issue. Apparently, the BIOS tells us we can control PCI Express hotplug, but then it tries to do that itself via ACPI at the same time and that leads to a GPE storm. We may try to poke the BIOS a bit differently than we do right now, but whether or not it helps is to be seen. Also, we can try to handle both ACPI-based and native PCIe hotplug simultaneously at the same port, but that's going to be tricky. We still can use DMI-based blacklisting as the last resort.
