It's something that's been there all along, and is finally starting to bite places where it never used to bite before. It's a latent bug in platform code, that's all. This "IRQ0 is bad" has been known for quite some while - you've already been pointed at Linus' rant about it, dated 25 Jan 2007. If you do a bit of research, you'll find that the orion code was contributed _after_ that date. While it's easy to stick a warning into orion_irq_init() (or whatever the function is called), it's utterly pointless now that it's been found - just fix all the users of orion_irq_init() now and be done with it. As for "shouldn't this have had a warning in the past", well, maybe, but consider this task: Please go and look at the other mach-* directories, and find all those which might use IRQ0, and arrange for them to print a warning. I'm sure you'll see what a task it is that you're asking for. What you're asking for is actually unreasonable. (I am aware that Dove broke exactly for this reason, and I've been carrying a patch since December 2014 to fix Dove - but I just don't have the time to get it merged - like most of my other Dove work.) -- FTTC broadband for 0.8mile line: currently at 10.5Mbps down 400kbps up according to speedtest.net.
