Hi,
it seems that PCI quirks are not handled on resume which results
in all kinds of strange effects, like disappeared PCI devices.
Below is a diff between "lspci -vvvxxx" before and after resume
for my SMBus device which only gets enabled by PCI quirk handling.

Besides that, a number of drivers do not restore the pci config
space of their associated devices properly on resume from S3.
These drivers (and associated devices) are:
- intel_agp (Host bridge: Intel Corp. 82855PM Processor to I/O Controller)
- ? (PCI bridge: Intel Corp. 82855PM Processor to AGP Controller)
- uhci_hcd (USB Controller: Intel Corp. 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) USB UHCI Controller)
- ? (PCI bridge: Intel Corp. 82801 PCI Bridge)
- ? (ISA bridge: Intel Corp. 82801DBM LPC Interface Controller)
- piix_ide (IDE interface: Intel Corp. 82801DBM (ICH4) Ultra ATA Storage Controller)
Diff between "lspci -vvvxxx" before and after resume for all
problematic devices on my machine is attached.
Are there any patches I can try?
Regards,
Carl-Daniel

The uhci-hcd driver _does_ restore the config space for its devices
properly.

Just because the before and after values are different doesn't mean
anything is wrong. Those particular bits are set by the hardware in
response to various events. They are used only by the BIOS, to provide
USB keyboard and mouse services. They don't affect the device's function
or the Linux driver at all.

Apparently something is sort of wrong though, because I need to rmmod
uhci_hcd and hci_usb before suspending, otherwise nasty things happen.

Can you be more specific? Start with the kernel version you're using.
What happens if you rmmod hci_usb and leave uhci_hcd alone? What shows up
in dmesg? What shows up if you set CONFIG_USB_DEBUG?

Hmm, it DOES seem to work with UHCI_HCD (in other words, it works if I

Tried and not happening anymore. This means I have been grumpy without valid
cause and you've been doing great work!
