The network card is no longer detected, and I get a lockup when removing the root bridge and rescanning. Partial dmesg output below. Significantly, the lines: > [ 0.152128] PCI host bridge /soc/pcie@0x01000000 ranges: > [ 0.152142] No bus range found for /soc/pcie@0x01000000, using [bus 00-ff] are new. Both series are applied to v4.1, use the same .config file, and the same dtb. I will investigate further. (Re-testing v2 works, so this isn't an interim hardware failure) Thanks, James root@localhost:~# dmesg | grep -i pci [ 0.126184] PCI: CLS 0 bytes, default 64 [ 0.152128] PCI host bridge /soc/pcie@0x01000000 ranges: [ 0.152142] No bus range found for /soc/pcie@0x01000000, using [bus 00-ff] [ 0.154183] imx6q-pcie 1ffc000.pcie: PCI host bridge to bus 0000:00 [ 0.154201] pci_bus 0000:00: root bus resource [bus 00-ff] [ 0.154215] pci_bus 0000:00: root bus resource [??? 0x01f00000-0x01f7ffff flags 0x0] [ 0.154228] pci_bus 0000:00: root bus resource [io 0x0000-0xffff] [ 0.154270] pci_bus 0000:00: root bus resource [mem 0x01000000-0x01efffff] [ 0.154306] pci 0000:00:00.0: [16c3:abcd] type 01 class 0x060400 [ 0.154333] pci 0000:00:00.0: reg 0x10: [mem 0x00000000-0x000fffff] [ 0.154352] pci 0000:00:00.0: reg 0x38: [mem 0x00000000-0x0000ffff pref] [ 0.154377] pci 0000:00:00.0: IOMMU is currently not supported for PCI [ 0.154429] pci 0000:00:00.0: supports D1 [ 0.154440] pci 0000:00:00.0: PME# supported from D0 D1 D3hot D3cold [ 0.154683] PCI: bus0: Fast back to back transfers disabled [ 0.154806] PCI: bus1: Fast back to back transfers enabled [ 0.154884] pci 0000:00:00.0: BAR 0: assigned [mem 0x01000000-0x010fffff] [ 0.154903] pci 0000:00:00.0: BAR 6: assigned [mem 0x01100000-0x0110ffff pref] [ 0.154917] pci 0000:00:00.0: PCI bridge to [bus 01] [ 0.155145] pcieport 0000:00:00.0: Signaling PME through PCIe PME interrupt [ 0.155161] pcie_pme 0000:00:00.0:pcie01: service driver pcie_pme loaded [ 0.155279] aer 0000:00:00.0:pcie02: service driver aer loaded [ 1.188840] ehci-pci: EHCI PCI platform driver [ 1.232518] ohci-pci: OHCI PCI platform driver -- To unsubscribe from this list: send the line "unsubscribe linux-pci" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
