It could until recently, due to my fault. I can revert the change that caused it, but haven't yet, because I don't understand why it's causing the problem. And I'm pretty confident it's not causing the mountroot issue (though, I was pretty confident it wouldn't cause any problem anyway, but that turned out to be false confidence). > > Dennis Clarke Can you somehow get a dmesg dump to post to the list? I'm very curious to see what could be causing the problem you're seeing. - Justin
