Date: Mon, 24 Dec 2007 06:12:46 +0100 From: Frans Pop <elendil@...net.nl> To: linux-kernel@...r.kernel.org Cc: linux-acpi@...r.kernel.org, Zhao Yakui <yakui.zhao@...el.com> Subject: pnpacpi: exceeded the max number of IO resources: 24 During boot with v2.6.24-rc6-125-g5356f66 on my Toshiba Satellite A40 laptop, I suddenly get the following message (repeated 22 times!): pnpacpi: exceeded the max number of IO resources: 24 Last time I tested 2.6.24 on that box was after the initial merge, but before -rc1. Then those lines were not present. Looks like the messages originate from a7839e96 by Zhao Yakui and that patch just adds the kernel messages so it was probably a hidden issue before, but I cannot determine if I should be worried or not. Possibly unrelated and harmless, but there's also a major change in reported iomem/ioport ranges (first 5 lines basically identical, rest new): -pnp: 00:00: iomem range 0x0-0x9ffff could not be reserved -pnp: 00:00: iomem range 0xe0000-0xeffff could not be reserved -pnp: 00:00: iomem range 0xf0000-0xfffff could not be reserved -pnp: 00:00: iomem range 0x100000-0x1ef3ffff could not be reserved +system 00:00: iomem range 0x0-0x9ffff could not be reserved +system 00:00: iomem range 0xe0000-0xeffff could not be reserved +system 00:00: iomem range 0xf0000-0xfffff could not be reserved +system 00:00: iomem range 0x100000-0x1ef3ffff could not be reserved +system 00:00: iomem range 0x1ef40000-0x1ef4ffff could not be reserved +system 00:00: iomem range 0x1ef50000-0x1effffff could not be reserved +system 00:00: iomem range 0xfec10000-0xfec1ffff could not be reserved +system 00:00: iomem range 0xfeda0000-0xfedbffff could not be reserved +system 00:00: iomem range 0xfec00000-0xfec00fff could not be reserved +system 00:00: iomem range 0xfee00000-0xfee00fff could not be reserved +system 00:00: iomem range 0xffb00000-0xffbfffff could not be reserved +system 00:00: iomem range 0xffe80000-0xffffffff could not be reserved +system 00:08: ioport range 0x1e0-0x1ef has been reserved +system 00:08: ioport range 0x480-0x48f has been reserved +system 00:08: ioport range 0x680-0x6ff has been reserved +system 00:08: ioport range 0x800-0x80f has been reserved +system 00:08: ioport range 0xd800-0xd87f has been reserved +system 00:08: ioport range 0xd880-0xd89f has been reserved +system 00:08: ioport range 0xd8a0-0xd8bf has been reserved +system 00:08: ioport range 0xe000-0xe07f has been reserved +system 00:08: ioport range 0xe080-0xe0ff has been reserved +system 00:08: ioport range 0xe400-0xe47f has been reserved +system 00:08: ioport range 0xe480-0xe4ff has been reserved +system 00:08: ioport range 0xe800-0xe87f has been reserved +system 00:08: ioport range 0xe880-0xe8ff has been reserved +system 00:08: ioport range 0xec00-0xec7f has been reserved +system 00:08: ioport range 0xec80-0xecff has been reserved +system 00:08: ioport range 0xeeac-0xeeac has been reserved Full dmesg and config attached.
