Thanks for doing the bsearch - it helps. There were no driver changes between 2.6.11-rc4 and 2.6.11-rc5. The only PCI change I see is --- drivers/pci/pci.c 22 Jan 2005 03:20:37 -0000 1.71 +++ drivers/pci/pci.c 24 Feb 2005 18:02:37 -0000 1.72 @@ -268,7 +268,7 @@ return -EIO; pci_read_config_word(dev,pm + PCI_PM_PMC,&pmc); - if ((pmc & PCI_PM_CAP_VER_MASK) != 2) { + if ((pmc & PCI_PM_CAP_VER_MASK) > 2) { printk(KERN_DEBUG "PCI: %s has unsupported PM cap regs version (%u)\n", dev->slot_name, pmc & PCI_PM_CAP_VER_MASK); and you're not getting that message (are you?) Nothing much in arch/i386.. There were some ACPI changes, which is always a worry ;) Does that machine run OK without ACPI support? If so, could you determine whether disabling ACPI fixes things up? - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
