For quite some time (a period of months) linux-next was broken and I had to carry a patch to ACPI to make it boot. I dropped that patch at the head of my stgit trees in all of my repositories. So I wouldn't be at all surprised to learn that eventually kernel-2 found that object in kernel-1. Sometime when I dropped that patch from kernel-1 (because it finally got fixed upstream) I can see how it broke. But now that patch shouldn't be needed by any tree since I have long since dropped it from the stgit stack. So if we cleaned up all of the useless objects in this tree I bet this object wouldn't be needed. Not exactly a situation that I'd expect git to be able to dig out of itself thought. I'm creating clean repos and going to do no work in my -alt :) Thanks everyone! -Eric -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
