No IRQ known for interrupt pin A of device 00:0f.0

Hi,
I just saw this warning when booting:

Uniform Multi-Platform E-IDE driver Revision: 6.31
ide: Assuming 33MHz system bus speed for PIO modes; override with
idebus=xx
ALI15X3: IDE controller on PCI bus 00 dev 78
PCI: No IRQ known for interrupt pin A of device 00:0f.0. Please try
using pci=biosirq.
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
ALI15X3: chipset revision 193
ALI15X3: not 100% native mode: will probe irqs later

Booting with pci=biosirq doesn't help.
Both test10-pre5 and test10-pre6 give this warning. test9 didn't.

Should I just ignore it or is it really a problem?
(My system seems to work ok)
