I started with this bug:
I filed this bug after a bit.
I've not seen any resolution to this. I've just switched the card out
for a different card, and placed the card into another system, where it
Alan Cox's last comment was "IRQ routing not IDE I suspect"
I haven't pushed it beyond this, but it may be the flaky motherboard
chipset. The VXtwo chipset is known to be a bit cheap.
