I've been getting a number of lockups lately, especially in windows, but also in linux and I think it may have to do with my irq assignments.

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.

so how do I fix this? preferrably at the bios level so that it fixes it in windows also (or if you also have a windows work around)
I have linux on an MD raid 0 on two PATA drives and windows on the integrated SATA raid.
EDIT: fixed bold tags
