Hi to everybody,

I would like to know if this is of some importance or not. I notedt
this meesage in the dmesg today when I tried the linux-2.6.10-rc2
kernel.

I use a Sony Vaio PCG-GRT816S on wich I added another 512MB of ram
and a wireles Dell TrueMobile 1300 minipci card.

ACPI: PCI Root Bridge [PCI0] (00:00)

Uncovering SIS963 that hid as a SIS503 (compatible=1)
Enabling SiS 96x SMBus.

ACPI: PCI Interrupt Link [LNKC] (IRQs 3 4 5 7 9 10 11) *0, disabled.
ACPI: PCI Interrupt Link [LNKD] (IRQs 3 4 5 7 9 10 *11)
ACPI: PCI Interrupt Link [LNKE] (IRQs 3 4 5 7 *9 10 11)

PCI: Using ACPI for IRQ routing
** PCI interrupts are no longer routed automatically. If this
** causes a device to stop working, it is probably because the
** driver failed to call pci_enable_device(). As a temporary
** workaround, the "pci=routeirq" argument restores the old
** behavior. If this argument makes the device work again,
** please email the output of "lspci" to bjorn.helgaas@hp.com
** so I can fix the driver.

Can somebody explain me what this pci routing thing is ?

Many thanks and please e-mail me as I'm not subscribed to the list.
