+Subject: x86/PCI: Ignore _CRS on Supermicro X8DTH-i/6/iF/6F
+
+From: Bjorn Helgaas <bhelgaas@google.com>
+
+commit 89e9f7bcd8744ea25fcf0ac671b8d72c10d7d790 upstream.
+
+Martin reported that the Supermicro X8DTH-i/6/iF/6F advertises incorrect
+host bridge windows via _CRS:
+
+  pci_root PNP0A08:00: host bridge window [io  0xf000-0xffff]
+  pci_root PNP0A08:01: host bridge window [io  0xf000-0xffff]
+
+Both bridges advertise the 0xf000-0xffff window, which cannot be correct.
+
+Work around this by ignoring _CRS on this system.  The downside is that we
+may not assign resources correctly to hot-added PCI devices (if they are
+possible on this system).
