I have a laptop (Dell 1501) where hard drive does not work unless MSI
is off. It's not hard to add pci=nomsi, and Grubby copies it to new
kernel's command line, but the downside is, it took me a day to figure
out what was wrong. It completely looked like a garden variety SATA
failure. Maybe we want to keep it on in Rawhide and publicise "look
at /proc/interrupts, check if count is zero"?
