[ACPI] No IRQ known for interrupt pin A ...

[Frederik N. <fr...@e-...>]

Hi to all,
With the acpi in vanilla 2.4.22-pre6 I'm getting this warning during boot:

PCI: No IRQ known for interrupt pin A of device 00:10.0

My machine is a laptop, compaq evo n1020v and this is the info for that device 
(00:10.0), taken from lspci -xxx :

ide is working fine though.
Now, is this warning a dangerous thing? I know little about ACPI that's why 
I'm asking here. If this is not relevant to this list please be kind and give 
me a link to a relevant place or to a manual, whatever.
