You seem to have completely misunderstood what I said. Or you just didn't read it carefully. You say "...is still seeing..." when the whole point of my email was to show that it didn't used to see two controllers and now it does. "still" is a completely inappropriate word to describe the situation. The nearest time bracket I have is also in my last mail... Correct behavior: FreeBSD 4.5-RELEASE #0: Sat Feb 2 16:27:47 MST 2002 Incorrect behavior: FreeBSD 4.6-RC #2: Thu May 16 11:53:27 MDT 2002 I'm sorry I can't narrow it down any better than that. I didn't notice the difference when it first started happening (when I upgraded my development machine weeks ago), because it doesn't seem to adversely affect my systems at all. I just happened to notice the difference yesterday because Vladislav's mail pointed out the difference on the same day I upgraded another machine from 4.5 to 4.6 and had boot logs handy to show the before/after difference. > Note that PCI interrupts can be shared. Yes. That's why I took care to point out that the difference wasn't affecting me in any way (perhaps because of sharing, perhaps because the difference is just misleading reporting at boot time). But Vladislav seems to be indicating that it IS causing him a problem of some sort. I was just chiming in with some documentation of the difference to help illustrate the condition he was reporting. -- Ian To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
