Is this failure with suspend to RAM or to disk? How about if you try this patch? http://linux-acpi.bkbits.net:8080/to-akpm/[EMAIL PROTECTED] patch -Rp1 from 2.6.12-rc1-mm and see if it stops being broken or patch -Np1 to 2.6.12-rc and see if it starts being broken. This one removes an earlier attempt at resuming PCI links -- now putting the onus on the drivers to be properly written to release and acquire their interrupt for a successful suspend/resume. In theory, this is taken care of something like this: driver.resume pci_enable_device pci_enable_device_bars pcibios_enable_device pcibios_enable_irq acpi_pci_irq_enable but if the patch above makes a difference, then theory != practice:-) I'd believe that ohci_hcd and ehci_hcd are fragile since glancing at their lengthy .resume routines it isn't immediately obvious that they do this. But yenta_dev_resume has a pci_enable_device(), so that failure may be less straightforward. cheers, -Len ps. if point me to a full dmesg -s64000 from 2.6.12-rc1 acpi-enabled boot, that would help -- for it will show if we're even using pci interrupt links (and programming them) for these devices on this box. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
