It seems like more and more problems with PCI MSI are turning up
in the 2.6.20 kernel. Discussion upstream concluded that maybe
it should have been off by default in 2.6.20, so maybe we should
just do that in Fedora and make people who want it use "pci=msi"
to enable it? It's probably not going to be really stable until
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"?
