(3) is https://bugzilla.kernel.org/show_bug.cgi?id=56531 > If that is case, we should have something like attached patch for it. It does not even compile because the argument of pci_bus_add_devices() points to a const struct. You can't increment a member of it. And even if you remove the const from both the declaration and the definition of that function, the patch doesn't help at all. Here is /proc/ioports with the fixed-up patch: 0000-0cf7 : PCI Bus 0000:00 0000-001f : dma1 0020-0021 : pic1 0040-0043 : timer0 0050-0053 : timer1 0060-0060 : keyboard 0062-0062 : EC data 0064-0064 : keyboard 0066-0066 : EC cmd 0070-0077 : rtc0 0080-008f : dma page reg 00a0-00a1 : pic2 00c0-00df : dma2 00e1-00e1 : #ENUM hotswap signal register 00f0-00ff : fpu 03c0-03df : vga+ 0400-0453 : pnp 00:04 0400-0403 : ACPI PM1a_EVT_BLK 0404-0405 : ACPI PM1a_CNT_BLK 0408-040b : ACPI PM_TMR 0410-0415 : ACPI CPU throttle 0420-042f : ACPI GPE0_BLK 0430-0433 : iTCO_wdt 0450-0450 : ACPI PM2_CNT_BLK 0454-0457 : pnp 00:06 0458-047f : pnp 00:04 0460-047f : iTCO_wdt 0500-057f : pnp 00:04 0680-069f : pnp 00:04 0cf8-0cff : PCI conf1 0d00-ffff : PCI Bus 0000:00 1000-100f : pnp 00:04 164e-164f : pnp 00:04 2000-2000 : pnp 00:04 2004-2004 : pnp 00:04 3000-5fff : PCI Bus 0000:08 6000-6fff : PCI Bus 0000:05 6000-60ff : 0000:05:00.0 6000-60ff : r8169 7000-7fff : PCI Bus 0000:04 8000-8fff : PCI Bus 0000:03 9000-9fff : PCI Bus 0000:02 a000-a03f : 0000:00:02.0 a040-a05f : 0000:00:1f.3 a060-a07f : 0000:00:1f.2 a060-a07f : ahci a080-a087 : 0000:00:1f.2 a080-a087 : ahci a088-a08f : 0000:00:1f.2 a088-a08f : ahci a090-a093 : 0000:00:1f.2 a090-a093 : ahci a094-a097 : 0000:00:1f.2 a094-a097 : ahci ffff-ffff : pnp 00:04 ffff-ffff : pnp 00:04 And /proc/iomem: 00000000-00000fff : reserved 00001000-0008f3ff : System RAM 0008f400-0009ffff : reserved 000a0000-000bffff : PCI Bus 0000:00 000c0000-000cffff : Video ROM 000d0000-000da3ff : Adapter ROM 000e0000-000fffff : reserved 000f0000-000fffff : System ROM 00100000-9ae3efff : System RAM 01000000-0166bfff : Kernel code 0166c000-01cbca3f : Kernel data 01dba000-026b8fff : Kernel bss 9ae3f000-9aebefff : reserved 9aebf000-9afbefff : ACPI Non-volatile Storage 9afbf000-9affefff : ACPI Tables 9afff000-9affffff : System RAM 9b000000-9f9fffff : reserved 9fa00000-feafffff : PCI Bus 0000:00 9fa00000-9fa00fff : pnp 00:09 a0000000-afffffff : 0000:00:02.0 b0000000-cfffffff : PCI Bus 0000:08 b0000000-c06fffff : PCI Bus 0000:0a b0000000-b01fffff : PCI Bus 0000:0b b0200000-b03fffff : PCI Bus 0000:0b b0400000-b05fffff : PCI Bus 0000:0c b0600000-b07fffff : PCI Bus 0000:0c d0000000-d03fffff : 0000:00:02.0 d0400000-d13fffff : PCI Bus 0000:02 d1400000-d23fffff : PCI Bus 0000:03 d2400000-d33fffff : PCI Bus 0000:04 d3400000-d43fffff : PCI Bus 0000:05 d3400000-d3403fff : 0000:05:00.0 d3400000-d3403fff : r8169 d3404000-d3404fff : 0000:05:00.0 d3404000-d3404fff : r8169 d4400000-d53fffff : PCI Bus 0000:08 d5400000-d63fffff : PCI Bus 0000:05 d6400000-d73fffff : PCI Bus 0000:04 d6400000-d6401fff : 0000:04:00.0 d6400000-d6401fff : xhci_hcd d7400000-d83fffff : PCI Bus 0000:03 d7400000-d7400fff : 0000:03:00.0 d7400000-d7400fff : rtsx_pci d8400000-d93fffff : PCI Bus 0000:02 d8400000-d8401fff : 0000:02:00.0 d8400000-d8401fff : iwlwifi d9400000-d9403fff : 0000:00:1b.0 d9400000-d9403fff : ICH HD audio d9404000-d940400f : 0000:00:16.0 d9404000-d940400f : mei_me d9405000-d94050ff : 0000:00:1f.3 d9407000-d94077ff : 0000:00:1f.2 d9407000-d94077ff : ahci d9408000-d94083ff : 0000:00:1d.0 d9408000-d94083ff : ehci_hcd d9409000-d94093ff : 0000:00:1a.0 d9409000-d94093ff : ehci_hcd e0000000-efffffff : PCI MMCONFIG 0000 [bus 00-ff] e0000000-efffffff : reserved e0000000-efffffff : pnp 00:09 feb00000-feb03fff : reserved fec00000-fec00fff : reserved fec00000-fec003ff : IOAPIC 0 fed00000-fed003ff : HPET 0 fed10000-fed19fff : reserved fed10000-fed17fff : pnp 00:09 fed18000-fed18fff : pnp 00:09 fed19000-fed19fff : pnp 00:09 fed1c000-fed1ffff : reserved fed1c000-fed1ffff : pnp 00:09 fed1f410-fed1f414 : iTCO_wdt fed20000-fed3ffff : pnp 00:09 fed90000-fed93fff : pnp 00:09 fee00000-fee00fff : Local APIC fee00000-fee00fff : reserved ffd80000-ffffffff : reserved 100000000-25fdfffff : System RAM 25fe00000-25fffffff : RAM buffer You can compare them with other files from https://bugzilla.kernel.org/show_bug.cgi?id=56531 -- Alexander E.
