We ran out of I/O space. We had 8K leading to the switch, but 4K go to the Realtek NIC, and 4K go to SATA: pci 0000:00:1c.3: bridge window [io 0xb000-0xcfff] to [bus 04-0d] pci 0000:05:05.0: bridge window [io 0xc000-0xcfff] to [bus 09] pci 0000:09:00.0: reg 0x10: [io 0xc000-0xc0ff] Realtek NIC pci 0000:05:09.0: bridge window [io 0xb000-0xbfff] to [bus 0d] pci 0000:0d:00.0: reg 0x10: [io 0xb050-0xb057] SATA It seems like there *is* I/O space available in the system, so I'm not sure why BIOS didn't assign enough here. But it's still a bug that Linux couldn't fix it. > The bridge is based on PLX PEX 8112(?) chip and lspci shows: > > 04:00.0 PCI bridge: PLX Technology, Inc.
