That's a bit strange. It looks like the registers changed after we had restored them during "early" resume. So either we hadn't actually restored them (it would be interesting to find out why), or they really changed (again, it would be interesting to see why). > -uhci_hcd 0000:00:1a.0: restoring config space at offset 0xf (was 0x100, writing 0x10a) > -uhci_hcd 0000:00:1a.0: restoring config space at offset 0x8 (was 0x1, writing 0x2081) > -uhci_hcd 0000:00:1a.0: restoring config space at offset 0x1 (was 0x2800000, writing 0x2800001) > -uhci_hcd 0000:00:1a.1: restoring config space at offset 0xf (was 0x200, writing 0x20a) > -uhci_hcd 0000:00:1a.1: restoring config space at offset 0x8 (was 0x1, writing 0x20a1) > -uhci_hcd 0000:00:1a.1: restoring config space at offset 0x1 (was 0x2800000, writing 0x2800001) > ehci_hcd 0000:00:1a.7: restoring config space at offset 0xf (was 0x300, writing 0x30b) > ehci_hcd 0000:00:1a.7: restoring config space at offset 0x4 (was 0x0, writing 0xe0641000) > ehci_hcd 0000:00:1a.7: restoring config space at offset 0x1 (was 0x2900000, writing 0x2900002) > HDA Intel 0000:00:1b.0: restoring config space at offset 0xf (was 0x100, writing 0x10a) > HDA Intel 0000:00:1b.0: restoring config space at offset 0x3 (was 0x0, writing 0x10) > HDA Intel 0000:00:1b.0: restoring config space at offset 0x1 (was 0x100000, writing 0x100002) > pcieport-driver 0000:00:1c.0: restoring config space at offset 0xf (was 0x100, writing 0x4010a) > pcieport-driver 0000:00:1c.0: restoring config space at offset 0x9 (was 0x10001, writing 0x1fff1) > pcieport-driver 0000:00:1c.0: restoring config space at offset 0x8 (was 0x0, writing 0xfff0) > pcieport-driver 0000:00:1c.0: restoring config space at offset 0x7 (was 0x0, writing 0x200000f0) > pcieport-driver 0000:00:1c.0: restoring config space at offset 0x6 (was 0x0, writing 0x80800) > pcieport-driver 0000:00:1c.0: restoring config space at offset 0x3 (was 0x810000, writing 0x810010) > pcieport-driver 0000:00:1c.0: restoring config space at offset 0x1 (was 0x100000, writing 0x100407) > pcieport-driver 0000:00:1c.1: restoring config space at offset 0xf (was 0x200, writing 0x4020a) > pcieport-driver 0000:00:1c.1: restoring config space at offset 0x9 (was 0x10001, writing 0x1fff1) > pcieport-driver 0000:00:1c.1: restoring config space at offset 0x8 (was 0x0, writing 0xe000e000) > pcieport-driver 0000:00:1c.1: restoring config space at offset 0x7 (was 0x0, writing 0xf0) > pcieport-driver 0000:00:1c.1: restoring config space at offset 0x3 (was 0x810000, writing 0x810010) > pcieport-driver 0000:00:1c.1: restoring config space at offset 0x1 (was 0x100000, writing 0x100407) > # These have moved down to late resume.

The problem is that pci_set_power_state() doesn't check if the power state is already correct before calling the platform to change it. The platform should cope with that, but it shouldn't be called for the second time at all. In fact I have a patch to change this behavior, but I consider it as a separate thing. > HDA Intel 0000:00:1b.0: PCI INT A -> GSI 17 (level, low) -> IRQ 17 > HDA Intel 0000:00:1b.0: setting latency timer to 64 > pcieport-driver 0000:00:1c.0: setting latency timer to 64 > pcieport-driver 0000:00:1c.1: setting latency timer to 64 > +uhci_hcd 0000:00:1d.0: restoring config space at offset 0xf (was 0x100, writing 0x10a) > +uhci_hcd 0000:00:1d.0: restoring config space at offset 0x8 (was 0x1, writing 0x20c1) > +uhci_hcd 0000:00:1d.0: restoring config space at offset 0x1 (was 0x2800000, writing 0x2800001) > uhci_hcd 0000:00:1d.0: PCI INT A -> GSI 20 (level, low) -> IRQ 20 > uhci_hcd 0000:00:1d.0: setting latency timer to 64 > usb usb5: root hub lost power or was reset > +uhci_hcd 0000:00:1d.1: restoring config space at offset 0xf (was 0x200, writing 0x20b) > +uhci_hcd 0000:00:1d.1: restoring config space at offset 0x8 (was 0x1, writing 0x20e1) > +uhci_hcd 0000:00:1d.1: restoring config space at offset 0x1 (was 0x2800000, writing 0x2800001) > uhci_hcd 0000:00:1d.1: PCI INT B -> GSI 22 (level, low) -> IRQ 22 > uhci_hcd 0000:00:1d.1: setting latency timer to 64 > usb usb6: root hub lost power or was reset > +uhci_hcd 0000:00:1d.2: restoring config space at offset 0xf (was 0x300, writing 0x30b) > +uhci_hcd 0000:00:1d.2: restoring config space at offset 0x8 (was 0x1, writing 0x2101) > +uhci_hcd 0000:00:1d.2: restoring config space at offset 0x1 (was 0x2800000, writing 0x2800001) > uhci_hcd 0000:00:1d.2: PCI INT C -> GSI 18 (level, low) -> IRQ 18 > uhci_hcd 0000:00:1d.2: setting latency timer to 64 > usb usb7: root hub lost power or was reset > ehci_hcd 0000:00:1d.7: PME# disabled > ehci_hcd 0000:00:1d.7: PCI INT A -> GSI 20 (level, low) -> IRQ 20 > ehci_hcd 0000:00:1d.7: setting latency timer to 64 > ehci_hcd 0000:00:1d.7: PME# disabled > pci 0000:00:1e.0: setting latency timer to 64 > +ata_piix 0000:00:1f.1: restoring config space at offset 0xf (was 0x100, writing 0x10a) > +ata_piix 0000:00:1f.1: restoring config space at offset 0x8 (was 0xc01, writing 0x2121) > ata_piix 0000:00:1f.1: restoring config space at offset 0x1 (was 0x2800005, writing 0x2880005) > ata_piix 0000:00:1f.1: PCI INT A -> GSI 16 (level, low) -> IRQ 16 > ata_piix 0000:00:1f.1: setting latency timer to 64 > ata2: port disabled. ignoring. > ACPI Exception (exoparg2-0445): AE_AML_PACKAGE_LIMIT, Index (000000005) is beyond end of object [20081204] > ACPI Error (psparse-0537): Method parse/execution failed [\_SB_.C2C3] (Node ffff88007e01dea0), AE_AML_PACKAGE_LIMIT > ACPI Error (psparse-0537): Method parse/execution failed [\_SB_.C003.C0F6.C3F3._STM] (Node ffff88007e043de0), AE_AML_PACKAGE_LIMIT > ata1: ACPI set timing mode failed (status=0x300b) > # Remaining differences are bogus: result of using wireless instead of wired networking.
