Possibly the test was broken. Did you have IRQF_DISABLED and
IRQF_SHARED flags set?
Given current experience maybe white-lists are in fact the way
to go.
Could it be whitelisted in the PCI driver side? I don't think it's
good to have a huge white/blacklist in each device driver.
Certainly, we should not have such lists in the driver. I don't think
anybody wants that.
