From: Russell King pci_assign_resource reports odd messages when resource allocation fails. This is because res->end and res->start are modified by allocate_resource. For example: PCI: Failed to allocate resource 1(0-ffffffff) for 0000:00:01.0 The following patch reports whether it's an IO or memory resource, and includes the correct size. For consistency, we report it in a similar way to the failure message in pci_request_region(), even though res->start is unlikely to be useful. --- drivers/pci/setup-res.c | 5 +++-- 1 files changed, 3 insertions(+), 2 deletions(-) diff -puN drivers/pci/setup-res.c~resource-allocation-reporting-fix drivers/pci/setup-res.c --- 25/drivers/pci/setup-res.c~resource-allocation-reporting-fix 2004-02-20 13:52:30.000000000 -0800 +++ 25-akpm/drivers/pci/setup-res.c 2004-02-20 13:52:30.000000000 -0800 @@ -143,8 +143,9 @@ int pci_assign_resource(struct pci_dev * } if (ret) { - printk(KERN_ERR "PCI: Failed to allocate resource %d(%lx-%lx) for %s\n", - resno, res->start, res->end, pci_name(dev)); + printk(KERN_ERR "PCI: Failed to allocate %s resource #%d:%lx@%lx for %s\n", + res->flags & IORESOURCE_IO ?
